FINALLY decided on a video card

[Hey Zeus]

She'll be here tomorrow. Thankfully so i can ship out these 9600's

Nice, I just bought a 5770 a couple weeks ago too, really wanted the XFX one but Sapphire had too good a deal going at the time to pass up.

Hey Zeus my super XFX 5750 vs your (hopefully super) XFX 5770.
Hmmm, I just noticed that monster cpu overclock you have.
Thats not fair. he hehe

Good luck buddy.

I've just been reading up on overclocking the 5770. Hopefully 1Ghz core and 4.9Ghz will yield some awesome numbers

let me know how easily the sticker peels off. i think i would want mine to just be black/red.

The 5770 has a powerful GPU, but it's severely memory bandwidth constrained. In order to feed the stock GPU (850Mhz), you need to overclock your memory by about 25%, think something like 6GHz. Overclocking your GPU to 1GHz will not help much in most cases, unless you can overclock your memory to about 6.8GHz. Anyways good luck 🙂

ATI should release a card with similar specs as the 5770 but with a 256bit memory bus, this way you get a card with similar performance as the 4890, but with less power draw and DX11 support. Maybe that card will be the 5830?

I disagree here. Overclocking my 5750's core (at 910) gave me much better results then with overclocking the memory from 1100 to 1360. Right now it has 88gb of bandwidth. Not bad considering my gtx 260 had 112 gb
Overall performance went up about 20%.

You see, the 5770 GPU has 11% more SPs and Texture units. Plus the clock speed difference 850MHz vs. 700MHz, 21% higher than the 5750. So overall, the GPU in the 5770 is over 32% faster than the one in your card (5750).

Now lets take a look at memory bandwidth:

5750: 128 bit / 8 = 16 bytes * 1150MHz * 4 = 73.6GB/s
5770: 128 bit / 8 = 16 bytes * 1200MHz * 4 = 76.8GB/s

So the GPU in the 5770 is 30% faster than the one in 5750, but has only 4% more memory bandwidth. Your GPU is fine with the memory bandwidth it has, but you can create the memory bottleneck I'm talking about by overclocking your GPU by 30% to 910MHz (it seems you already did that), and keep the memory at stock, 1150MHz.

Anyone know the link to unlocking MSI afterburner? XFX's bios will only allow me to goto 960c, 1440m on stock volts

You picked a nice video card, I really like the XFX Radeon HD 5770
