GTX 275 from XFX, 640 or 670 Mhz?

[Powerman287]

I have bought a new PC recently with the GPU GTX275 and i think i would like to buy another one to go SLI. the only thing i need to know is which one i have to buy... the one ive got now is the one from XFX with 640 mhz and i guess the one with 670 is better but does it increase performance all in all if i get one with 670 mhz instead of the same 640 mhz? or does it even decrease as it isnt the same? because as far as i can see the one with 670 Mhz is cheaper :S

Also i would need a SLI bridge to get the best performance but i cant find any whereever i look... could anyone suggest me somewhere to get one? i would prefer one of the flexible ones...

Thanks in advance

if u go to the SLI this will surely increase the performance.......therefore with a 670 Mhz ............this will be better

okay, so 640 mhz is better than 670 mhz when the one ive already got is also with 640 mhz?

the Gtx 275 at 670 Mhz is the more performance one .....go 4 it

oh lol of some reason i thought you had typed 640 mhz, sorry XD but do you think that even if the one ive got now has got 640 will it then affect the performance? i mean will 1x 670 mhz and 1x 640 mhz perform better than 2x 640 mhz? or will the 640 mhz on the first example just pull the 670 mhz down? ^^

the 670mhz one will underclock to a 640mhz spec'd

okay so technically i should just buy the cheapest right?

 

[dead_95]

it dont really matter it will just increase just the power consumption,performance ......etc by 3 or 4 %

get the same exact card and SLI.....

both cards are the same, the only difference is that one is overclocked 30 mhz more than the other.... by purchasing the 670Mhz version you will not gain any performance whatsoever if it is intended for SLI...

Or you may be able to increase the clockspeed of the lower card, either way just run the slower card in the secondary slot. What motherboard are you using?, as you should have got an SLi bridge with the board.

thanks for the replies

The motherboard i am using is called Gigabyte EX-58 UD3R, and yes i know there should have been a SLI bridge with it, but of some reason i didnt get any :S although i just spoke with the one i bought the pc from and he will send me one so it shouldnt be a problem anymore
