Questions about PC Upgrade

Hi all,

I am the proud owner of a DS rig already!
Current running:

i7 860 at 3.78 overclocked
EVGA P55 FTS MB
4 Gigs ds ram
XFX 6850 BE GPU

I mostly play World Of Warcraft and going to play Diablo 3 when if finally comes out. My main question is should I just upgrade my current PC or would it be worth going with a totally new rig we this config?

Please I am looking for honesty since this would be a major purchase for me. All feedback is welcomed.

Agreed, no need to upgrade your whole PC. It's only limiting factor right now will be it's PSU, which you didn't list.

If it has a big enough PSU you could either grab a second 6850 to run in Crossfire, or the other option is to just replace your 6850 with a bigger single GPU.

Hey guys,

So out of curiosity, would it be better to go crossfire xfx 6850 black edition or go with a higher graphic card? It a different card, what do you recommend?

Thank you for any replies.
