Core i5 750/ATI 5850 vs Core i7 860/5870

Hello all. I'm planning on building a new system within the next two or three months and I'm sort of undecided.

I have everything set except for the CPU/GPU. Here's what I've decided on:

Case: NZXT Tempest
MOBO: Gigabyte GA-P55-UD4P
RAM: 2x2GB G.Skill Ripjaws DDR3-1600 (Will add another 2x2GB down the road for 8GB)
PSU: Corsair 750W 60A +12v rail
HDD: Western Digital Caviar Black 640GB (+ my existing 250GB Seagate Barracuda)

I have a 23.6" 1080p (1920x1080) Asus monitor (Model VH242H) Would a Core i5 750/5850 suffice to play games at native 1080p with high to very high details (Games like crysis, fallout 3, stalker, mass effect 2, COD:MW2 and future games) Would the performance gain of a Core i7 860/5870 be worth the extra $$$?

Whatever I decide, I'm planning on adding another card for crossfire when prices drop at least $75.

Thanks for the advice! :bounce:

  1. Since you're already committed to the Crossfire route I'd vote 860/5850 now.
  2. Have you picked stuff up yet? IF you haven't there are new MoBo's coming out in 21 days, with THX onboard. Should be really nice. No prices yet though. Big Bang is the name, i'm pretty sure. These will also provide excellent support for multi-gpus, both sides green and red.

    If you want to see how the 50 stacks up to the 70, check out tom's review, with benchmarks for a lot of major games out now:,2433-6.html

    And I am with WR2 - go 5850, as you already have xfire in mind. Two of those will be a really powerful machine.
  3. You wouldn't recommend a 5870? I assume a 5870 would be a bit more 'future-proof' than a 5850. And a dual 5870 setup would be epic.
  4. Well, yes it would. I guess it comes down to your budget. two 50s is pretty damn good, but obviously two 70s is even better. I mean, if you want to max out games for a nice long time, the 70s is probably the way to go. Bang for your buck, the 50s are probably slightly better, but if you have the money, there are gains to be had with the 70.
