LoL!

Sure did! Right now, I'm kinda lean because I'm reconfiguring everything. So I only have a few of my GPUs actually folding at the moment. But once all my servers and machines are back up, I will have...

3 x 8800GTS 512
3 x 8800GS
2 x 9600GSO
2 x 9800GT
2 x 8800GT
1 x 8600GT
1 x 9800GX2
1 x HD2600 Pro

...and I'm looking to snag myself one more 9800GX2 in the near term so that I can run Quad SLI on my gaming rig. After that, I will be left with 6 unpopulated PCIe slots, which I will slowly but surely fill up depending on what's available at a good price. No rush on that though, so once I source another 9800GX2 I will consider myself "done" for the timebeing.

haha very nice!
Im just starting and am planning to build my first folding only rig.
It will have a 680i board along with a 9800GT and 2 x 8800GT's.
Running one of the cards on the 8X PCI-E lane should be fine right?

Noob to this :)

How much PPD are you getting with all that?

Im trying to snag up a cheap 9800GX2 from somewhere
And im dumping it all in my girlfriends house since her electricity is included in her rent

Yeah no problems there. I actually ran a little test over the weekend with the DFI UT P35-T2R I just bought off of S_G with an 8800GS card (at stock). The board has three slots - one at 16x, one at 4x and one at 1x. With the same WU, I did 20% in each slot, and the 8800GS got the exact same PPD in the 4x slot as it did in the 16x slot, and it lost only about 10% off its PPD in the 1x slot. So anything 4x and above will get you the same results, and even a 1x bus is usable for folding purposes.

I really have no idea what kind of PPD I will get out of everything once it's all going full-blower. I'm pretty excited to find out though! I'm still waiting on a few items, but I hope to have my server room back to 100% by the end of November.

I plan to get a simple E2160 for folding those 3 cards, do you think it will hold up? or will it bottleneck them?

My single GPU2 client on a 9800GT is already using 50% of an E8400 when running...

CPU has little to no impact on performance with nvidia's core. ATI's core is a completely different ball of wax, as it uses the CPU quite extensively.

I had at one point two 9800GT's and an 8800GT all running off a single core Celeron 440 at the same PPD they would have had if they were given their own cores on something faster. I think I remember reading that the rule of thumb is 4 nv GPU clients per core before you start seeing a significant slow-down in PPD.

So yeah - you could put all three cards on one of the e2160's cores, and still fold with the CPU uniproc client on the other core if you were so inclined.

great thanks! Thats good to hear.
