Our Ask the Experts section has a new question, where we have Tony in Australia wanting to know how he should proceed with his GPU upgrade.
Q: I want to improve my gaming performance although I have very empty pockets, I currently have a Gigabyte Radeon HD 6870 1GB Super Overclocked now. I have enough money to buy a Gigabyte Radeon HD7790 2GB Overclocked, but I'm hesitating because I can also buy another Radeon HD6870 1GB. I'm not sure whether the CrossFired cards would be much better although I'm having trouble finding another HD 6870 but i can find a HD 6850 (can the two diff cards be used in CrossFire?)
