The 5870 seems to be better (I only glanced) but its a hell lot more expensive, and you probably won't even notice the difference between the two. I would just go the 5770 based purely on bang for your buck reasons.
And I hope your running a 64bit operating System! 6BG of ram won't handle in a 32bit.
Ok the 5870 is obviously much faster/expensive than the 5770 as the 5770 is ati's last gen. But i am wondering if two 5770's will beat a single 5870 if ran in crossfire. Also why wouldn't i run 64-bit on a fricken i7 build?
Haha, when I built my first computer, it was top of the range. I had a Q6600 which was freaking awesome. Didn't even know about 64bit operating systems. Only found out when the windows 7 beta came out. Had been running a 32 bit copy of XP up until then
SLI is for those of Gods! I run it (well not at the moment, my hard drive shat out), and I think it would. I don't have much knowlege with graphics cards because they always get out dated within 2 months. So I would wait for another person to step in. Or you can go to SLI Forums, I learnt most of the stuff I know about hardware from there. They are all enthusiasts as well, will give you a definate answer within 2 seconds.
I think i'll just wait for someone else to step up here. I can't be arsed to sign up for yet another forum.
Yeah fair enough. I hate it when people tell me to go to forums as well. Its such a pain in the ass! I don't mind joining up, but most of the time I'm in the middle of something else and cbf to start again without much say in conversations etc etc. (post count = power)
Indeed. It is also awkard going from root-admin to someone with 31 posts but I digress.
In theory unless the 5870's are more than twice the power of the 5770's Two 5770's are a better deal.
Exactly. And not many cards that have been released that close together are that powerful, unless its gout 2 cores. NVidia brought out some like that a little while ago. Annoyed the hell out of me because it instantly outdated my system. And you could run them in Quad SLI!
Even with cards coming out so fast and outdating the old ones you can still run older cards and get the same if not better performance for the same if not cheaper price if your using SLI or Crossfire.
If only newegg still had the 5870 x2's in stock.
This Website
That website will let you compare cards(crossfire/sli also), you can just put up 2 5770's against 1 5870 and see the results.
EDIT: I just put up a 5870 against 2 5770's, the 2 5770's match the 5870's specs exactly.
Look in the spoiler for the results. BTW the 5770's, there are 2, it just doesn't show it in the pic.
