SLI- graphic cards

Marinenachrichtendienst · 01-02-12, 10:55 AM

In jan. 2011 I bought this PC:

- Intel Core i7 Quad Processor i7-870
- Sapphire Radeon HD 6950 2GB GDDR5
- Corsair Vengeance DDR3 1600MHz 8GB CL9
- Corsair Vengeance DDR3 1600MHz 4GB CL9
- Corsair Vengeance DDR3 1600MHz 4GB CL9
- Gigabyte GA-P55A-UD4, Socket-1156
- Corsair TX 750W PSU
- NZXT Phantom Big Tower (white)
- Windows 7 - 64bit

(Broadband: 70mps/10mps)

My graphic card:

Sapphire Radeon HD 6950 2GB GDDR5
PCI-Express 2.0, 2xDVI, HDMI, 2xmini-DisplayPort

I'm considering buying the same card for sli, but the closest choice for a new card that are more or less similar to mine, is :

Sapphire Radeon HD 6950 2GB GDDR5
PCI-Express 2.1, 2xDVI, HDMI, DisplayPort, Dual Fan and BIOS

Question:

As far as I have found out, is that the only difference with these 2 cards, is the "PCI-Express 2,0" and the "PCI-Express 2,1".

So, if I buy the new graphic card, would they run smoothly together, or will there be any sort of complications ??

Thanks in advance !

PS! Maybe my card is more than enough for SH5, and only waste of money to buy a similar one ??

As far as I can tell SH5 doesn't even support SLI, and I'd say that it indeed is overkill.

What I already have is "overkill", or "overkill" to sli to cards ??

It's overkill to get another one to go SLI

Isn't SLI an Nvidia thing and CrossFire the ATI equivalent?

It seems rather overkill as it is to me, anyway. Not that that's a bad thing...

Ran it pretty high on the old 8800GTS, just 1 6950 should be plenty.

Since SH5 doesn't support SLI or Crossfire, it would end up running on 1 card anyway, so for just SH5 I'd stay clear of multi-GPU solutions.

And yes, for Radeon it's actually Crossfire. Iirc it generally has better performance and is more flexible with setups, though I don't know about compatibility.

(I bet it's the same story; games either work well with multi-GPU or they don't)

Thanks for quick and detailed replies, everyone.

As for SH5, I better leave it as it is. Everything runs smooth, so there are nothing to complain about....
