I've read here and other places that while my single 16x PCI2.0 slot is obviously faster than the other 8x slot right next to it in my system........... it sounds like the speed difference isn't as much as I was thinking?
originally, when I replaced my 9800gx2 with an EVGA 480 superclock+, I was intent on selling the 9800gx2 and getting a physx card to pair with my 480. then, someday in the future when I get a 2nd 480 superclock+ (and a 3rd 28" hanns-g monitor for nvidia surround 3d), I could keep on using that PhysX card alongside my SLi 480.
then I realized my 2nd pci slot is only 8x. and I freaked out, got depressed and decided not to add anything at all...
so now I'm kinda confused.
A) in terms of performance, how much slower IS the 8x slot compared to a 16x PCI slot?
B) whats the best card to grab for a PhysX-only role? I've heard talk about an 8800GTS being a good choice. then i've heard talk about a 260 card being good for it. but, and I'm only looking at this in terms of price points... it looks like I could get an EVGA GeForce GTX 460 for about the same price. and obviously, I don't know what makes any card better for PhysX than the others - but I'm assuming that a 400 series card should perform better than a 200 series or especially an 8000 series.... right??
ESPECIALLY, someday relatively soon, when I upgrade the mobo/cpu/ram and get a rig going with 3 or even 4x PCI 2.0 16x slots.
so in conclusion I have the money that I'm going to make, selling the 9800gx2, along with some other spare parts... which looks like it should be about $150 or 200. and I'm willing to spend.. it for a PhysX dedicated card, that is, as long as my current motherboard (which is a DFI LANPARTY UT P35-T2R) can make proper use of it (or at least, make enough use of it, that it's worth my $$ right now)
what do you guys think? is there a clear cut answer here? I'm guessing that 8x is.. 75% or 80% as fast as 16x from what I've read, and to me, that seems like a reasonable performance rate, to justify getting a $175 card for PhysX (I'm being an nvidia fanboy/PhysX optimist here, I'm thinking & hoping that more and more games will take advantage of it like Mafia 2).
