It's clear that after the release of the GTX 460, companies have chosen to kick up the overclocking side of things another notch. We're seeing companies really offer us some huge overclocks, with some coming in not all that far from its maximum overclock. And while that means there's not as much to play around with, it means that you're able to get almost maximum performance out of a card without the need to tinker with it, which for some people is just perfect.
The biggest issue with SLI and Crossfire is that when you start going down those paths, you're adding more heat into the mix. As soon as that begins to happen you're hindering your maximum overclock ability. With these cards being clocked not far from the models maximum OC when in single card form, you're not finding that much more head room when it comes to overclocking further when in SLI. You combine this with the fact that you're going to be running more voltage through the cards and even more heat is generated, you'd probably be almost best to leave a card and setup like this at the reference clocks.
The picture would be different if the core clock was 800MHz, but it's not; it's 888MHz, and Galaxy has taken the time to bump the memory to 4000MHZ QDR which we've said before was a great decision.
Considering the performance you're able to get out of this setup for $300 US, it really is quite amazing. Throw in the fact that it's just cool to have multi GPU / card setups and you're onto a winner. The GTS 450 in SLI, like the GTX 465 is performance on a budget, and not budget performance.
There's a large gap between the GTS 450 and GTX 460, which means there's a very large gap between the same cards when running SLI. While a single GTX 460 overclocked to over 900MHz might be better value than a GTS 450 SLI setup, the latter setup is going to offer more performance for a price tag that isn't much higher.
NVIDIA has ultimately provided a setup for the $300 US price bracket while also creating a great card for people who want to spend under $150 US, and while AMD intend to start launching the HD 6000 series from October, word is they'll start at that mid $200 US mark the GTX 460 is at, and not this budget friendly $150 US mark.
