Ok, so picked up a GTX260 today and loaded her in. After a clean scrub of the old drivers and a fresh install she seems to be working like a charm. Currently have her tackling a 1680, has yet to complete a frame but it downloaded about a minute ago. If this turns out all well and stable (I'll know by about 10%) I'll start up the E6600 proccy with the SMP client. I may be in debt for the next month, but a GTX260 for $135 USD is impossible to turn down. Especially seeming how it appears I didn't get screwed in the deal. This added into my 9800GTXs and E8500s score should be nice. Next up will be gently OC'ing everything. Oh, I'll also get GPU-Z and find out if this baby is 192 or 216, but even if its a 192, still a stinking good deal.
Edit: Some snags. I'm only pulling 4500 PPD on a 1680 pointer. My 9800GTXs pull 5500 on these. Any help you guys have on getting this ironed out would be great. System specs:
XP 32 Bit
E6600
DP965LT (shitty but it shouldn't be a problem)
4 x 1 GB Kingston Ram (was originally a Vista x64 box, .5GB doesn't matter to me)
Antec Truepower Trio 650W
XFX GTX 260 192 SP stock clocked 576 gpu / 999 mem / 1242 shad
Seagate 80GB 2.5" Drive

Nothing but the GPU client running. Running across DVI->HDMI to my TV. Same scores going across S-Video. GPU-z and Riva Tuner temp reports 51 C on stock cooling which is all wrong by itself. The motehrboard is old so its only going to be PCI-E gen1, but its still x16 and shouldn't be any problem. Tell me, should the VDDC current fluctuate between 16-41A? I've never actually looked at this page before. Also it does seem to have an intermittent capacitor whine, but from searching the web many people say 'don't worry about this'.

-advmethods, big files, low instead of idle. Everything else I believe was just left as is.
