Alright, put simply, I'm building my own computer (finally) and it's going to be unstoppable.

I've already procured a BFG GeForce GTX 260 on clearance (no it's not broken) and I'm looking at a 3.4GHz 4-core AMD processor, etc.

I don't have a hard disk as of yet, but it would be big enough that I can dual boot. Probably will do that anyway.

So, I was looking through the Applications page here on MW@H, and I must say, it's laid out horribly. I have no idea what some of the category headings are there for, or what they even mean. And it seems like some things are repeated.

Plus, I was confused as to the ATi vs NVIDIA compatibility. I know that MW has ATi apps. I know there are CUDA apps. I just couldn't figure out on what OS the CUDA apps will run. I saw Linux, which is fine because I have a 10.04 CD lying around and I like Ubuntu and all. Thing is, I'm thinking about getting Windows 7, and I'd just like to know if I can crunch in CUDA, with my GTX 260, on Windows 7 or Ubuntu 10.

As it stands, I crunch on a 4-core i5 on a Mac system where my GPU is compute 1.2, so I've not yet used GPU will MW. PrimeGrid, for reference, consistently sends me CUDA tasks in batchs of 20 that complete with few errors. Given I'm building a computer around gaming and crunching...wanna know what I'm in for.

Thanks for helping me get things sorted out; any info is appreciated.

Oh and I probably should have thrown this in, but I love how the nbody apps are now multi-processor. That leads me to believe I can crunch your WUs on just about anything...the processor I'm getting for my beast machine is pretty fast and all, but I still need to be sure there are CUDA apps for Win7 or Ubuntu (or some Linux flavor)

I was running a GTX260 on Windows 7, now exclusively running Seti.

Not sure about Linux, but I was runing my ati GPUS on suse for a trial until I reverted. Can't see why cuda would not work with linux.

Ok, great...pretty much all I need to know.

As long as I can crunch this project in CUDA on any OS, that's fine. The GPU is mainly for a) games made past 2004 and b) Photoshop and other such applications with GPU algorithms...the free time in the processor I want to use for MW@H, etc.

Thanks for the reply.

MW@H cuda app works with GTX260 + XP, Win7
