Hey! I'm about to upgrade my 4 years old rig with a few parts. I want to be sure if my old parts can handle XFX 6950 XXX 2GB Edition.

ASUS P5B
Q6600 @ 3ghz (or maybe more, getting a new cooler, such as mugen III)
4gb ddr2-800 (upgrading to 6 or 8 aswell)
palit geforce 8800 gts 640mb (going to remove this one, epic card served me well :] )
dvd writer/burner
320gb sata II drive
few fans

NEW CORSAIR CX V2 500W Power supply

I'm aware that I have PCI-E 1.0/1.1 slot in this motherboard.

1. How 6950 (PCI-E 2.1) FPS gets affected with 1.0/1.1 supported mobo?

2. Also is my other hardware such as q6600 a bottleneck?

3. Corsair 500w cx v2 power supply enought? with 34 amps on single 12v rail

4. Does 6950 card work in my mobo (since old pci-e slot)?

5. Is it possible to shader unlock this 6950 xfx 2gb XXX edition card to 6970? How power requirements go and will the psu still handle it? :/ 

Bottom line: Is it worth going from old nvidia 8800 to shiny new xfx 6950? is it in terms of 'overkill' ?

Thanks in advance :)  -AkZu

1. How 6950 (PCI-E 2.1) FPS gets affected with 1.0/1.1 supported mobo?
Not sure- hopefully someone else can address specific numbers on this.


2. Also is my other hardware such as q6600 a bottleneck?
If you overclock your processor, it will provide similar gaming performance to more modern processors. Not exactly the same, but you'll be in the same ballpark.

3. Corsair 500w cx v2 power supply enought? with 34 amps on single 12v rail
Should be ok, but it never hurts to spend a few more dollars and bump up to a 550w or 600w to be on the safe side. Meets minimum required psu and corsair makes solid units.

4. Does 6950 card work in my mobo (since old pci-e slot)?
A 2.0 card is backwards compatible but you may experience lower performance.

5. Is it possible to shader unlock this 6950 xfx 2gb XXX edition card to 6970? How power requirements go and will the psu still handle it?
Not sure but I wouldn't bet on unlocks with non reference cards these days. Power requirements don't change unless you bump them using powertune.

Bottom line: Is it worth going from old nvidia 8800 to shiny new xfx 6950? is it in terms of 'overkill' ?
What resolution will you play at? You will experience massive performance increases. However, I would note that the 6950 1GB performs identically to the 2GB version and is significantly less expensive.

I'd recommend finding a similar version of the 1GB card and going with it! You may be limited somewhat by your mobo, but you can always replace that at a later time as needed. My .$.02

Very big thanks! Cleared most of my questions :) !
I'm running my pc on SONY 32" KDL32-W5500 tv, @ 1920x1080
If that 500w is really pushing it I don't know.., it's been 3 months since I bought it (after old one was destroyed by lightning strike). I'm kinda tight on budget :/ 

But I really wanna feel it coming down from 90nm process to 40nm after few years it can be very amazing upgrade :)  (I had dream of upgrading whole computer to new level after nvidia 600 series and ivy bridge comes out, but don't have money for that right now)

Let me share my own experience with a Q6600 bottleneck. It's going to be simple since I can't remember my other specs of the old system.

Pre upgrade this is what I had:

Q6600
9800 GTX

I upgraded to an HD 5850. I had a gaming performance boost of about 10% with the new card. Once I upgraded to an i7+asus p6t, the difference was night and day as far as gaming performance goes.

I would not want a 6950 paired up with a Q6600, ever.

I've read some of the benefits of the next gen cards coming next year are supposed to take away some potention from CPU bottlenecks. I'd recommend looking into what's around the corner if you're not going to be upgrading your CPU. The Q6600 is ancient.

Take a look at some of the marks

Ok, thanks. I might save money untill I get around 1200 € to fully upgrade my rig for powerful 600-series gpu from nvidia and ivy bridge and such. Since my hardware so old, best thing is just to do full update I guess :/

I think you can have a powerfull system way cheaper than 1200 euro's. Just use some stuff you allready have, like the psu and stuff. The new 600 series will use less power and can be handeld easely with the 500W Corsair.

@ Beltzy ; a 6950 is not a 2.0 but a 2.1 card, sometimes they have isseus with a 1.0 mobo. Not often, but still.
