5870 cf vs 7970

post #1 of 12
Thread Starter 
I have two 5870's and i was looking into getting an 7970 and maybe selling my 5870's. I don't have much money at the moment and i'am not sure if it is worth buying a 7970 in my case. Performance wise, how big is the gap between a 7970 and 5870 cf.rolleyes.gif

5870 CF is going to be faster over all compared to the 7970, but you could easily overclock the 7970 and be them out right.

I wish i could overclock my 5870's.I cant even go 900/1300 instead of stock 850/1200 because the driver drops the clock when the cards are not used and my screen flickers like crazy!!!mad.gif

OP get a HD 7950. at the same clocks HD 7950 is 3 - 5% slower than HD 7970. a HD 7950 overclocked to 1.1 Ghz matches HD 7970 Ghz (1.05 Ghz) and will be faster than HD 5870 CF. In the most demanding DX11 games and highest settings like BF3, Crysis 2, Metro 2033 HD 7950(1.1 Ghz) will be faster than even a HD 6970 CF. Also with a single HD 7950 you can avoid multi GPU issues like microstuttering. You also are not dependent on CF scaling for performance. there are games when CF just plain does not work and also where performance scaling is not googd. In those cases its even worse for HD 5870 CF. And with the HD 7950 you get a card which draws less power and runs much cooler than HD 5870 CF. thumb.gif

I would say to go for it. The extra VRAM will make a massive difference in newer games with high-res textures. For example, I used to have 5870s and when I did, I had problems with games like GTA 4 and such that used a lot of RAM. Obviously there are even more games now, like Skyrim etc. that would make that gap even more noticeable. Not to mention if you're running at higher than 1080p that RAM will be really useful to you.

I made the jump from 2x5870s to a single 680, man, what a difference in newer titles and I love not having to worry if the game supports crossfire.

Honesltid grab a 7950 if your short on cash it has massive overclocking headroom and is very comparable to the 7970 at same clocks

Seem about right, do you know when the new gen amd cards come out? im thinking of just replacing my cpu and gpu at the same time once i have around a thousand .

(i7 930 is not much and overclocker, or i just have a bad chip)

about Q1 - Q2 next year the new 8xxx series cards should be released and the next gen of intel (haswell lga1150 sck) will be released around Q2 if you want to wait smile.gif

if you want a card now the 7950 is probably the best price per performance ratio right now.
