My brother has a 7770GE @ 1300mhz and gets 17865 for the Graphics score for 3dmark vantage using the P setting. Card can take on a highly clocked GTX460 with ease. Card is a pretty decent low power card that can still pack a punch. Get a 7950 and call it a day.

This card is going for $300 on NCIX.ca , http://www.ncix.ca/products/?sku=67546&vpn=GV-R795WF3-3GD&manufacture=Gigabyte&promoid=1210 the cheapest GTX 670 is about $360 after MIR ($10).
So... ?

PS: How easily can I OC the 7950 (without having to change the volt and all of the other fun stuff) ?

Gigabyte HD 7950 comes with stock clocks of 900 Mhz . Overclocking in AMD CCC without voltage control is very easy. Enable AMD Overdrive in the Performance tab in AMD CCC. max out power control to +20% . AMD CCC allows overclocking upto 1.05 Ghz for the HD 7950. Test for stability using BF3, Heaven 3.0, 3DMARK 11, Crysis 2.

With voltage control and an app like Sapphire trixx or MSI afterburner you can get this bad ass chip to 1.15 - 1.2 Ghz. If you want to know how a HD 7950 at 1.2 Ghz performs.

Ah man, I think you just bought me with that, is my PSU good enough for OCing? Also is there a guide (in more detail) that explains what you just said above? smile.gif

PS: I was reading the review and it said, that those speeds on the HD 7950, are very rare to get with your average 7950 card, is the one i showed about good enough to get at least 80% of that OCing? Also I have air cooling.

OP the MSI HD 7950 twin frozr from newegg ca has the best price you can get and is unbeatable in terms of value for your money. the cooler on the card is good for clockspeeds upto 1150 Mhz . The Gigabyte windforce cooler is better and can handle 1200+ Mhz overclocks. here is a Gigabyte HD 7950 user running at 1200 Mhz for 24/7 gaming

I can pick up this card (store is close to my house) for $338 including taxes and what not.

http://forums.us.ncix.ca/products/?sku=67546&vpn=GV-R795WF3-3GD&manufacture=Gigabyte&promoid=1210

and the one you recommended including taxes + S&H for $318

http://www.newegg.ca/Product/Product.aspx?Item=N82E16814127667

For a $20 difference I think I should go with the Gigabyte, right?

PS: This might sound stupid, but are there ANY advantages on purchasing a GPU that it's from the same brand as the MOBO? (In general)

yeah get the gigabyte HD 7950 OC from ncix . definitely the better option and worth the extra 20 bucks.

The thing i do like about ATI cards.. Is ALOT of the older aftermarket GPU coolers will work on them(Even though it doesnt say it) I put a OLD Zalman VF1000 cooler on the 7770! And it worked wonders for my temps smile.gif Just remember, that MOST ati GPU's r pretty much the same, From the older cards to the newer cards(From what ive seen) and you could get a card that has stock cooling(If its cheaper and get a older aftermarket HSF and have great cooling(Better than most stock) smile.gif

Now im not 100% sure if all ATI GPU's are the same size, Its just from what ive seen with my own exp biggrin.gif
