GT 640 2Gb or GTX 650 2Gb or GTX 650tI 1Gb for PhysX?

post #1 of 6
Thread Starter 
Like the thread title asks...I want to pair this up with a GTX 670 (more specifically for Borderlands 2) so I can get as much eye-candy as possible.

Save a little money, the following more than enough: EVGA 01G-P4-2650-KR GeForce GTX 650 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130827

My buddy uses a GTX 260 with his SLI gtx 580s and it never runs greater than about 40 - 50% utilization.
I have a GTX480 I can let go cheap if you're interested.

The following are Gigabyte GPU's
GT 640 - 89.99 (69.99 after rebate)
GTX 650 2Gb - 127.99 (107.99 after rebate)
GTX 650Ti 1Gb - 159.99 (139.99 after rebate)

Those above are the choices & I have a $15 gift certificate to use @ MicroCenter smile.gif

Now why would I want such a power-greedy card like that, especially for PhysX thinking.gif ... Not thumbsdownsmileyanim.gif

Welcome to the boat my friend! Lol.

I have been researching and researching PhysX cards to pair with, in my case, a 670FTW, but which will also be able to keep up with 2 and 3 way SLI of the aforementioned cards. I figure that 4way SLI scaling is so bad considering the cost that a dedicated PhysX card would be a great addition to my rig.OrOriginally, it was going to be an LSI or 3ware Hardware RAID card, but I don't have enough room for the drives in my current case, so PhysX it is.

There are two things that I have determined are most crucial to the PhysX card providing substantial benefits, which are:
1) Number of CUDA Cores Relative to the Primary GPU(s) - the sweet spot seems to be around 50-70 percent
2) Clock Speed of the PhysX Card - the higher the clock speed (and thus shader speed), the better the results

The 650Ti 1GB cards seem to provide the best performance of all the available options. I have been looking at the EVGA 650Ti SSC which is clocked higher than the majority of the cards out there, and which has a substantial benefit over the 640 in terms of CUDA cores.

The amount of available VRAM seems to have absolutely no effect on performance, so I would not waste money on a 2GB version.

The benchmarks I've seen have shown that the 650Ti beats almost everything else, even cards that cost significantly more, when paired with the 670/680 cards.

Honestly, I'm just not interested in the 480 despite how much you sell it for wink.gif
