I have an older ASUS P4C800-E Deluxe motherboard, and want to know what the yellow RCA port on the back does
Hey guys, I've got an older ASUS P4C-800-E Deluxe board, and I wanted to know what the yellow RCA port on the board's connectors is actually for. Is it an input or output, and how can I use it?
The yellow port on the back of your ASUS P4C800-E Deluxe motherboard is an S/PDIF port. It is used solely for digital audio. These ports are commonly found on motherboards, and act as a digital output port for audio. This means you can play digital audio such as Dolby Digital 5.1, or DTS tracks from a DVD for example through the S/PDIF port.
It will allow you to plug an appropriate coax cable into the port, and into an audio/video (AV) receiver. The AV receiver would then decode what it passed through the port (the audio track) and output it as intended from your source (DTS, DD5.1).

Hi! I'm building my first computer and i was wondering if a MSI Radeon HD 7770 video card is compatible with an ASUS M5A97 motherboard.
Yes, an MSI Radeon HD 7770 will definitely work on your ASUS M5A97 motherboard. The ASUS M5A97 motherboard is actually CrossFire-compatible. This means you could put another HD 7770 into the motherboard in the future, and enjoy close to double the performance of the single HD 7770.
The ASUS M5A97 motherboard has PCI-Express x16 slots, which means you can put virtually any video card on the market into the motherboard. But being CrossFire-compatible, it gives you a great upgrade path going into the future.
I am building a new desktop pc wich will have a 2 way SLI setup on it, and was wandering about if it is worth getting a mobo that can run these two cards at x16 both or just x8 both. I am casual gamer and wanted to know if it will make much difference in gaming if the cards run at x16 or x8. The cards are at moment Msi's gtx 560 ti 2gb.
Thank you for your time, cheers!
This is another great question, Severus! I wouldn't really recommend specifically going out and buying a board that is capable of running multi-GPUs in x16 mode, as the performance benefits really aren't that great.
If we were talking PCIe 3.0 hardware, and some multi-monitor, multi-GPU gaming, maybe... but even then, we're talking less than 10-percent improvements across the board, most like 4- to 5-percent improvements. If you haven't already bought the GPUs (you say you're buying a new desktop PC) then I would save the money and get a board that doesn't cost that much (all boards have a single x16 port at least) and spend the money from the two GPUs on one single, faster GPU.
This way, you could get something like a ZOTAC GeForce GTX 670 for just $399.99 from Newegg. GeForce GTX 560's are still around $170 each, meaning a single GPU is only a bit more, but you do gain more performance from a single GPU, and less troubles with scaling and game compatibility, as well as not needing to worry about SLI for now.
Then, when you're ready for SLI, your motherboard will handle dual x8 ports, and you can throw another GTX 670 in it for some serious horse power.

Do you have to have a 120Hz monitor (as opposed to a 60Hz) for 3D gaming?
Great question, Chris! This is something that NVIDIA and AMD don't really specify on their boxes, and can be a bit confusing when choosing not only a new GPU, but a new TV or monitor. First up, both companies use different forms of 3D technology, on NVIDIA's side we have 3D Vision, with AMD using HD3D technology.
In order to use NVIDIA's 3D Vision technology, yes, you will require a 120Hz monitor. This is because NVIDIA's 3D Vision uses an active shutter system, where each lens of the 3D Vision glasses operates at 60Hz, giving a better 3D experience, not just for the game itself, but your eyes. NVIDIA's 3D Vision also requires 3D Vision-compatible displays, rated at 120Hz.
AMD's HD3D on the other hand, is a much more open environment. They don't restrict 3D to specific "AMD HD3D-compatible" screens, which makes them a viable alternative to NVIDIA's 3D Vision. AMD just need 120Hz, but the glasses can be from the monitor manufacturer, and not specific AMD HD3D models.
There are some monitors that will reportedly work at 1080p but just 30Hz (60Hz total, screen limit) but this would result in a sub-par experience, not just for frame rate, but the 3D would most likely not look good at all. Our recommendation is to get a proper 120Hz screen. Even if you were to get a 3D Vision-compatible monitor, you're not locked to just NVIDIA's 3D, you can always use AMD's... it just gives you a monitor that has more life in it, and then you can upgrade in 1-2 years time and not have to worry.
I hope that's helped you!
What's the best value for money video card to buy right now? I game on my 46" Full HD TV and play mostly FPS, I'd like to spend less than $300.
Great question, right now you're sitting between a great number of GPU choices from both AMD and NVIDIA. NVIDIA have their great 500-series, and 600-series, so you could scoop up something like the MSI GeForce GTX 570 Twin Frozr II, for just $249.99 from Newegg.
On the Red Camp, you could grab MSI's Radeon HD 7950 Twin Frozr III card, which sports 3GB of RAM for $319.99 after Rebate from Newegg, a little out of your $300 budget, but the performance is worth it, and it would last you until next-gen games arrive. This card sports 3GB of RAM, too, so you could crank the AA and AF in your games without worrying too much of performance loss.
With either of these GPUs, you could run most games maxed out at your TVs resolution of 1920x1080, with the AMD card however, you have enough VRAM to crank the AA and AF settings to max in most games, without losing much performance. This is because the Radeon HD 7950 has 3GB of RAM versus the GeForce GTX 570s 1.2GB of VRAM.
But, you have two choices there - one from NVIDIA, one from AMD. We're not biased, but both video cards perform great and will last you for a considerable amount of time for the future. I'd be leaning more toward AMD, simply because it's a newer card, on a newer architecture, with more features, more RAM and a quieter, better cooler.
But, if you like NVIDIA, the GTX 570 is definitely no performance slouch!
