Res. 1920x1200 For a dedicated physx card, does the amount of on board memory affect performance? All else equal would there be difference between 512MB vs 1GB?
I was recently asking the same question, and all of the information I found pointed to no, the extra memory would not help in physx. However I bought a 1GB card anyway over a 500MB as it was only a small difference in price and I may use the card in the future for something other than just physx. Hope this helps
Don't spend the money, it's not worth it for the tiny number of games that support PhysX hardware acceleration (two big-ish games in the last year I think? Batman and Metro 2033?). If you read into the marketing bullcrap it might seem like a good idea, but unless you really do just have money to throw away you won't see much of a benefit in games.
