OK, so given that I can spend about $220 in total, which option is better for GPUgrid?

2 9800GT 512MB cards (EVGA, 512M, stock clock 600)

or

1 GTX260 (MSI, 896MB, OC'd to 575 from factory)

I would say get the GTX260.

-support double-precision 64-bit floating point computation
-less watts = 182 for gtx260 while 2 9800GT has 210 combined

Count another vote for the GTX260:

- more future proof (64 Bit, more memory, + whatever is included in the higher CUDA hardware capability version number)
- slowdown of interactive usage should be (almost?) unnoticeable
- current WU times strongly depend on the software config, so it's difficult to tell.. but the GTX260 may actually be a bit faster

Vote for 260.

- just one PCIe in use. It means in future you could use more 260`s



But take 260 Core 216
