Questions:

When I do crossfire my 4870's will the EA 650W have enough power?

The 4870's will be running at 8x/8x, will they bottleneck?

Is there a noticeable difference at 16x/16x?



Total comes to around $900 with shipping

I wouldn't run two 4870's on the EA650. I would say a 750w PSU at a minimum. I would go for this PSU, its $110 after using the Promo code, and after $30 MIR its only $80, which is an awesome deal.

Alternatively, You could just get that Case/PSU combo and just go lighter on the GPU's. Two 4850's in crossfire will be plenty for 1080P resolution.

Running at X8 bandwidth for crossfire makes very little difference unless you are going quadfire (4850x2's or 4870x2's), it makes maybe a 1% FPS difference to go with X16 X16 with 4870's.
 
+1 to xthekid and shortstuff

+1 for 4850 crossfire...Actually you can get 2x4850 for about $190 now...SO for just $6 more, you get considerably high performance and for the 1080p, 2x4850 is more than suffice...it would play all the games maxed out @ that resolution...

So if you go with 2x4850, then you wouldn't have to change the PSU also...

And as shortstuff said, dont change the RAM...AMD CPUs take advantage of that speed...
 
Good luck getting your hands on 2 4770s though, and right now 4850s tend to be a bit cheaper and a lot easier to find in stock and the 750Watt power supply give him far more room to upgrade in the future
 
Those HIS GPU models with the IceQ4 fans on them exhaust their heat; I think worth paying a little more, especially if you think you'll want a pair of them (that's a lot of heat).
