am looking at getting a 9800GT for seperate PhysX processing but am now stumped at the specs between these 2 cards. http://www.novatech.co.uk/novatech/...idia/Nvidia9800Series/Novatech/9800GT1GB.html http://www.novatech.co.uk/novatech/...ia/Nvidia9800Series/Novatech/9800GT512MB.html can anyone help me in deciding as i dont know whether or not the more memory in the first one is better or the faster GPU and memory clock speeds of the second are better. my current graphics card is a GTX 260 898MB Thanks in advance.
don't waste your money, nothing good uses PhysX and most games use Havox or use there in game engine to do all the physics
Well there is a 1GB (the first link) and a 512MB (the second link) The one with more RAM will be more powerful But only buy a bit as the difference in price shows. I don't know what you want to spend but the better one is the 1GB version. Not sure if thats what you were looking for...
Don't bother. The GTX 260 runs Physx just fine for the games out at the moment. In the future when you upgrade a seperate Physx card would be pointless anyways as the newest high end cards runs everything max and runs physx by itself.
I agree with Zero_UK. Fermi card look so far to be VERY powerful.. even too powerful for games today... so it will have plenty of free resources to do physiX without any worries... But, for now the GTX260 should be more than enough for max setting gaming with PhysiX.. the time you'll really need to change Fermi basded architecture GPU's should be more affordable.
more stream processors and faster core clock will give better dedicated physx performance. Memory and memory clock is almost irrelevant. http://www.tomshardware.com/reviews/batman-arkham-asylum,2465-8.html the gts 250 which is very similar to the 9800gt gives the best physx performance without having to buy another gtx 260. Notice how at the bottom of each graph it shows the performance of using physx on the same card the graphics are rendered on... quite a difference.
