Currently I'm running an i7 oc'd to 4.0ghz, 6 gigs of ram, and a gigabyte ud3R mobo that has 2 pci-express 2.0 slots (supports crossfire natively, sli with bios update), 750 watt corsair psu. Oh ya, and win7 64bit.
My primary game (75% of my gaming time) is WoW but I do enjoy messing around with other newer games like Mass Effect 2, bioshock 2, dragon age, cod, stalker, etc.
Right now I'm running a single 4870. I have a few choices I'm looking at to upgrade:
A: buy another 4870 and run them in crossfire (~150$)
B: buy a 4870x2 and run it in crossfire with the 4870 i already have (~450$)
C: buy a 5870 (~400)
buying 2 5870's or a 5970 are more than I'm willing to spend. I know WoW doesn't support dx11 but i'd like to have good framerates on those other games as well and any games i'd like to buy in the future. Will the 4xxx series last me awhile or should I upgrade to dx11 right away.
Is your 4870 struggling with what you currently play? If not I would go with option D) Do nothing. Then when it starts to struggle hopefully GPU prices have dropped a bit
Direct x 11 is not a big deal yet, so again I would not bother buying a new card if your current one does fine
If your 4870 is struggling (I would be surprised if it was, my 8800GTX was still running things fine on high quality), personally I would grab the 5870, you have a very nice system, having old technology for your GPU seems a shame.
There is absolutely no need to buy 2 5870s or a 5970, possibly in a few years but not now.
my monitor is 1920x1080. I don't really *need* to upgrade but I'm just about done with my deployment in Iraq and I feel like blowing some of that money on the weakest part of my system.
the 4870 plays everything fine but some games I can't crank to the max settings. It actually has trouble with WoW at completely max settings in a raid, WoW's graphics have really gotten better in the last few years. With the new expansion I forsee myself needing the upgrade if I want to continue at max settings.
A 4870 is a lot cheaper than a 5870 and two of them would give me probably more performance in most games but the 4xxx series will only last me another year maybe while a 5xxx will last me longer.
I think I'm probably going to go with the 5870 solely for the reason that WoW doesn't support crossfire and sli setups yet. I might not gain as big of a performance boost in other games compared to a 4870x2 but oh well. Spending more for (percieved) less just makes me cringe though.
