SLI or dedicated physX

post #1 of 37
Thread Starter 
Ok well i'll have a new rig pretty soon and will have a 570 to start, I really like the effects PhysX brings to the table but i'm not sure what would be more beneficial, to have a second 570 or say a gtx 260 c216 as a PhysX card? Will be gaming at 1080p

grab a second 570 and put it in sli and the physx will be taken care of by the cards while still giving you a performance boost

SLI 570's can easily handle PhysX too. So SLI. Although a Phenom II quad won't handle 570 SLI all that well, even at 4.0GHz.

SLI with physx gives better results than single+physx.

Also the fact that some games barely use the physx, or not at all, the best benefit is to add a second card to SLI them.

Hmmm ... now, which is better thinking.gif Adding a 2 year old, $90 card that'll add like 20% performance on approximately .005% of all games, or adding a new $350 card that will boost my performance by 70-90% on like 99% of all games I ever play?

This is a tough one headscratch.gif

Believe it or not, for my rig, I prefer to play Mafia 2 with my SLI set split and dedicated physX on one card. However, Mafia 2 is a very special case in that there's an extra benefit to having an actual dedicated physX card. Any other case ... I totally agree with you wink.gif

Don't worry my new rig will have a 2500k...but also something i'd like to add, from a money standpoint it would be awhile before i could get enough for another 570 to SLI, would it be worthwhile to have a dedicated physx card in the meantime or would that just be a waste of money that could be put towards the new 570?

It depends. Do you only play Metro 2033, Mafia II, Just Cause 2, or Unreal 2003? Those are the only games (off the top of my head, there's like maybe 2 more) that support PhysX fully.

If you already HAVE say an 8800GT or stronger card, then it wouldn't hurt to use it. I wouldn't spend the money on a card dedicated for PhysX though. Not when your 570 will already do it fine.
