So my mate has a 5770 atm, it's not terrible he plays with a 27" 1080p monitor and a second monitor at some lower res ~720p ball park is buying a 2nd 5770 going to be a value for money upgrade? or would he be better off spending more on something like a 6850. I don't think he minds not having maxed out settings but at least medium to high on new games at 1080p is what were looking to accomplish. atm a 5770 looks like it'll cost around $100. He's just spend $600 upgrading to an i5-2500 rig and trying to keep this as cost efficient an upgrade as possible.
I would say YES 5770 over 6850 Save himself +-$50 and get about the same performace abit better actually then the 6850. Unless he wants to wait and save himself $160ish and wait for PCIE 3.0 but $160 wont get him a new mother board and video card. So $ vs FPS go for 5770 my personal opinion!
Well he just bought a new mobo with the i5-2500 that has pci-e 3.0 I just saw a compatibility chart that said 6770 can be crossfired with 5770, would 6770/5770 beat 5770x2? or is there no real difference at all between them and thus why they work together?
Well if he has a PCI-E 3.0 its really up to him if he wants to wait 4-8 months for the new ones to come out. spentshells has a good point also could sell it and buy just Bigger Card. SLI/XFIRE sound really awsome but theres alot of bugs still in them, unless u like technical challenges(like myself) go for it. BTW u cant Xfire 6770 with a 5770 if u read that somewhere its false. ONLY Cars with the same FIRST TWO No. can XFire like 5770 with 5750 or 6770 with 6750 (57XX with another 57XX///69XX with another 69XX)unless the changed that recently!
