EuroFight Posted July 28, 2012 Posted July 28, 2012 Hi everyone, I have just bought an Inno3D GeForce 8600 GTS (I appreciate it is an old card, but this will be made clear as I go on). I am also planning to buy a higher-spec AMD card in the future. I was wondering if I could use a CrossFire bridge on the SLI port on the 8600 to improve the PhysX performance of the system. Is this possible and what would I need to get it to work? I have no knowledge of CrossFire or SLI, so sorry if this is a stupid question. Cheers, EuroFight Share this post Link to post Share on other sites More sharing options...
Muchoman1 Posted July 28, 2012 Posted July 28, 2012 Unfortunately no, you cannot crossfire or sli between card manufacturers, between series (eg a 580 and a 480) or between models (580 and 570) If you get a Higher spec Nvidia card, you can use your 8600GTS for PhysX, you will not need to use the SLI bridge, however, a 8600 GTS will not be of any benificial performance when used for PhysX, in fact, it will probably slow down the system 1 Share this post Link to post Share on other sites More sharing options...

Muchoman1 Posted July 28, 2012 Posted July 28, 2012 It simply depends. In the video card market, you generally get what you pay for from a performance standpoint. The faster cards are more expensive, and the more expensive cards are usually faster (TJJ_Angel or someone will nitpick my argument here with some odd examples) but generally that is how it works. For low-medium end cards in the budget range of a 7770, the 7770 is probably the best card, however if you can stretch your budget to a Nvidia 560 it will be much faster for not much more money.

EuroFight Posted July 28, 2012 Posted July 28, 2012 Ah, well, I will keep an eye out for deals on a GeForce 560 or a HD7770, and will probably go for the cheaper of the two Thanks for all your help +1 Share this post Link to post Share on other sites More sharing options...

A 580 can SLI with a 570 and a 6950 will CF with a 6970. The higher card just down tunes it self to be like the lesser card Also you can CF and SLI with different manufacturers, I had a EVGA and BFG 8800GT SLI in my system for while. Check your facts.

The higher card just down tunes it self to be like the lesser card Also you can CF and SLI with different manufacturers, I had a EVGA and BFG 8800GT SLI in my system for while. Check your facts. No check YOUR facts... AMD allows certain different models to be in CF together like a 5850/5870 or 6950/6970 or 7950/7970 but this is absolutely NOT true for Nvidia. You cannot SLI a 570 with a 580 nor a 670 with a 680... Heck AMD allows a 6990 to cf with a 6970 when Nvidia doesnt even allow it's 590 to SLI with a 580 Different manufacturers like an EVGA 580 with an ASUS 580 are allowed as it is still a 580 Edit : Also, the higher card does not downclock itself to the lesser card. I had my 5970+5870 running at different speeds in CF and with my EVGA SC 580 with a normal EVGA 580 both cards actually ran at the SC card's clocks Edited July 28, 2012 by Midnight Rider Share this post Link to post Share on other sites More sharing options...

So there is not really any point. Share this post Link to post Share on other sites More sharing options...

Nyt Posted July 28, 2012 Posted July 28, 2012 And just for the OP, using an Nvidia card for PhysX with an AMD card used to be possible with hacked/modded drivers but it is really too much effort to even consider it now-a-days 1 Share this post Link to post Share on other sites More sharing options...
