ATI Radeon HD 4870 X2

is ATI Radeon HD 4870 X2 compatible with my current system without bottlenecking?

heres my PC specs;

850 watt PSU
amd athlon 64 x2 5600 processor
4gb DDR2 ram = corsair 6400.

my current graphics card is an ATI radeon 4870 1gb gddr5. i thought about upgrading a motherboard that could support dual GPUs for crossfire but then, i could also just replace my 1gb GPU to a single graphics card with 2 GPUs. which is the best move? money wise, just getting a dual GPU is better than getting a motherboard and another graphics card.

im running my PC with windows 7 ultimate.
this is my server for my PS3 too using TVersity and PS3 media server.
my games are as follows;
COD MW, MW2, MW3, world at war, couter-strike source, unreal tournament III.

thanks a lot for the help guys.

  1. I personally would grab a new mobo + a new proc.. pretty sure thats whats holding you back, that slow dual core.
  2. okay thanks man. i'll just leave my old system alone and build a new one. i already have them line up on my newegg account. i really want the six core with crossfired GPUs.

    System upgrade would be preferable indeed. Not worth putting 4870's in crossfire though. I'd choose something with directx11 support. Also when you go crossfire remember 2x 1GB videomemory is NOT 2GB videomemory. The same texture information just gets loaded twice, only each board will be responsible for drawing parts of it. The videomemory isn't put into one memory pool which is shared.
