i found a good deal on 2 4870x2 graphics cards but im not sure if they are worth it . will i be able to use all 4 of them in battlefield 3 . I've heard about so many problems and they take a lot of power (423w @ full load) .

More about : 4870x2 crossfire

Depends how good the deal is and if you already have a power supply that can handle it and cooling.

The people I've seen talk about those cards have a hard time spending cash upgrading. The only real downside is that you will be limited I believe to DX9 or 10?

Quad GPU's don't scale very well and you will probably only get at most the performance of three, not to mention the possibility of microstuttering.

The 4000 series are now a much older architecture and they don't even support Direct X 11.

Depending on how good of a deal you're getting on them, your best bet might be to skip on the deal and get a single HD 7970 which alone can get ~100 fps on Ultra details. (Source, Tomshardware 7970 Benchmark) You will also eliminate any possibility of Microstuttering.

:o  7970 thats $600

the 2 4870x2 are $160 . it can play dx11 games its just that there's no tessellation . and i there isn't a lot of micro stuttering on 4xxx gpu. i could sell my 6850 for about 120-140 without postage and my current psu to get a 975w + psu

$160? SOLD.

I was expecting maybe $300! At $160 that's a damn steal

if you already have a 6850 just get a second one of them the 6 series scales alot better than the 4 series cards not to mention noise and power issues, i previously had 4850 cf and i was forever having dramas with bf bad company 2 trying to get a stable driver even to 4850's got hot and noisy together 2 4870x2 would be unbearable in my books! currently have 6950 and running bf3 @1680x1050 (all my 22 will do) at ultra settings with out the noise and heat of the 2 4850s and it runs ALOT quicker

well i found an even better deal 5970 for $260 . so never mind this but i would like to know if 650w is enough . most of the reviews say the systems total consumption at is 400-500w at FULL load . and my cpu is only 95w
