GTA IV performance is still horrible after all these years despite AMD rep saying that it's a driver problem that could've been fixed. I guess they "forgot". I'm starting to feel like getting a Nvidia card.

Come on man dont be one of those guys... Most manufacturers use Elpida memory now. Mine wont go over 1500 no matter what and i can only run that in 720p benching. max 1450 in 1080p games. You got what you paid for. How good is your core?

I agree. You could've gotten just as bad of an overclocker from any other company too. If it runs at stock you got what you paid for.

Based on my 4 day turn around including shipping time on my rma with sapphire, I'd recommend them again in a heartbeat.

I have 4 7950s with Elpida Vram best of all of them only does 1525mhz.

The rest have hynix and the avg on them is 1700mhz on vram.

" not that i care about Vram " the core is more important in almost everything beside a token game here and there and benching.

Not entirely true. It depends on your resolution. At 1080p yes you're right. At 2560x1600 or eyefinity, vram speed does make a difference. Stock vram speeds should suffice though.

So basically. on 1080p screens i should get as far as i can on core and then try some on memory?

Yes. Even at higher resolution i only gained a little going from 1375 to 1850 on my memory.

My card doesn't have VRM temp sensors and no memory overvoltage. Only way to overvolt the core is using buggy Trixx which forces 3D voltage even when PC is idle. I'm not the only one with this problem. I hate companies that use sub-par PCB's that are worse than reference. Former Sapphire 7950 cards that had 7970 PCB may have been good but this card is disappointment, plain and simple.

My core overclocks to 1175MHz, that's pretty good I guess.
