video card is good but why not get his 6950 2gb for the same price ? i dunno but i will make my friend chose what he want xD
cpu is good also and that what he was looking @
It does take a lot of power, but you're current PSU has a great efficiency rating according to AnAndtech's review. Also it's enough to power SLI 560 Ti's OC'd. I just refer to the 570 because the 560 Ti OC'd is better than/equal to a stock 570. But still the 560 Ti OC'd uses less power.
The 6950 2GB OC'd can get to the 6970 if you're lucky. Since you need to unlock it to get there. So far I haven't seen huge OCs with the 6950 so that is why I recommend the 560 Ti, plus it runs a lot cooler and more stable.
