Worth it to CF an HD 7770 2GB?

post #1 of 6
Thread Starter 
Hey gang. I've got an ASUS HD 7770 2GB paired with a Phenom II X4 955 @ 3.6 Ghz (C2 stepping - this is all it can manage) on an AM3 mobo. Monitor for that PC is 1680x1050. The card is good for a budget one, but its a bit pokey at times and Newegg has them on sale at the moment (could get it shipped and rebated for $105). I think it would be on par in games that have decent CF profiles with an HD 7870 or GTX 580. Being it has a 2GB frame buffer, does it sound reasonable to crossfire?

Sure, just watch your power draw on that 560 watt psu.

That Seasonic Gold X-560 can run about 650-700W if it needs to. wink.gif Actually, I've got a PC Power and Cooler Silencer 750W in that particular PC, so no power worries.

I would say no, from my own experience, GPUs don't scale very well... I recently just got rid of my 2x HD7970s as the XFire performance just wasn't worth it. Very few games actually scaled well and often new releases were unplayable in XFire for a few months till ATI sorted their drivers out.

You'll be far better off selling the 7770 and getting a 7950 which will perform better in every game than spend similar for sometimes no increase in performance.

just my 2cents.gif

Annoyingly when looking at benchmark results and on paper, XFire looks like a no brainer as the average FPS is much higher but often the minimum fps is much more varied and ruins the gameplay. It can feel like it's running at 20fps when its running at 60. The term is microstuttering if you want to google it.

yeah i agree. sell the HD 7770 and go for HD 7950. some crazy deals for USD 250 or lower. massive 3 GB VRAM. close to 2.5x the perf of HD 7770 especially at avg overclocks of 1100 - 1150 mhz.

Think you all are right here. Its a "spare parts" PC - I may just leave it intact and give it to a family member soon vs. sinking any more cash into it.
