Reasons Why GPU Folding Rules...

Today I starting thinking about GPU Folding and why it seems like such a good idea. Here's what I came up with:

1. Does a lot more work (for science) than CPU Folding

2. Huge boost in PPD

3. That $400 video card now gets used 24/7 instead of 1 or 2 hours a day

4. Video cards will retain their value better, even after they won't play the newest games at uber resolutions

5. I can buy a Cross-Fire mobo and not feel guilty

Anyone have more?

 
I agree 100%. I have 4 dual core folding machines and I plan on getting an X1900 or X1950 for each one (2 1950pro's are on the way). I will have to upgrade 1 powersupply to get all 4 up.
 
6. Throws enough heat to keep my computer room nice and toasty, this way i dont have to turn on a 1500watt baseboard heater.

That's a good one, completely forgot about that.

My SFF and Opty 165 do this too.. but I put out fewer PPD than a dual core box with a GPU by about 50%.
 
7. My mother survived breast cancer.
8. My bestfriend and second mother figure died from cancer.
9. Because my help gives others hope

All the reasons I need.....

If I own it, I fold it

Your girlfriend / wife/ significant other is a lucky person. I always try to trick my GF into folding my laundry. Since we both hate it, we have "folding parties" a couple of days after all our laundry is done :D

oops >.< did I miss the topic ;)
 
a) Grandmother died from Parkinson's
b) Grandfather died of Prostate Cancer
c) Grandmother died from bone cancer
d) My GFX card would be idle otherwise...and we can't have that
e) Every little bit helps

The "huge" boost in PPD is not all it seems.
Running gpu folding on my X2 means sacrificing 2.5 ghz of cpu folding power just to feed the gpu.

The overall benefit varies depending on what cpu units are doing the rounds at the time.
EG: If 600 pointers were plentiful I would be sacrificing 300 cpu ppd to feed my 1900xt which gives me a lil over 400 ppd. (not that great a boost for best part of £200)

I suppose gpu folding is more beneficial with lesser cpu's.

So, if one factors that in, the overall ppd is greater than cpu only folding but not that much greater.

If you switch to Linux and go smp instead of gpu that's an instant 587 ppd per core. That's over 1000 ppd and a bonus, you cpu runs cooler.

So far I'm pretty impressed with the SMP client :)

you only said that so that I go to the dell refurb site and purchase myself a C2D system, did you not?

Well actually those numbers aren't quite right. You get 660PPD with a 1900xt (each WU is 330pts). With a little overclocking you're looking at 700+PPD.
My X2 running at 2.3GHz takes about 60hrs to do a 600 pointer, so that would be ~240PPD "lost"(or 300PPD in your case)
Net gain for me - 460PPD

Thats about what my Calculator got also ~450ppd increase by losing one core and adding a gpu
