Sapphire 7950 runs slower than R9 270?

[dave37694]

I got a a used Radeon Sapphire 7950 from a friend of mine. He hasn't used it in a while and overclocked a few times with it. When I put it in I downloaded all the latest drivers and ran it on Battlefield. And it averaged about 28-40 fps on it. He doesn't know what's wrong with it either. Can anybody help?

Sorry I put this under Windows 7. I don't know how to change it.

It could be heat problems, as well as you bottlenecking the GPU with your CPU, also an R9 270 is the equivalent of a 7870, with less power consumption, you also want to note that it is newer, also when you compare the R7 270 with the 7950 the differences are really kind not THAT important, it should be noticeable though, here a reference link for the comparison

also please note the 7950 requires more POWER from the PSU, so please if you could input your rig, please do, so i can kind of tell you what is going on, give us eyes cuz we are blind on this side of the screen

Cpu: Fx-8320
Psu: Evga 500w 80plus (upgrading to 600w later)
Ram: Kingston Blu 8 Gb 1600mhz (my motherboard pushes the mhz down to 1333. I can only get 1600mhz when overclocked)
Motherboard: MSI 760GMA-P34 (upgrading to full atx board later)

change your CPU

why? the 8xxx series are power hungry but good, plus he already has that cpu who would spend even more money on one of the most expensive parts of a PC, my guess is it can me either your motherboard (not that probable), your PSU (more probable, the 7950 requires a lot of power) or the card itself, if it is running slower than an R9 270 then your friend might have screwed up the card, plus the R9 270 is not bad at all, if your PC is stable with that card, i would not upgrade a thing (except, maybe, PSU) it's not like you are going to notice an amount in performance when you change to a 7950 (at least not a big one)
