    Guys,

    Planning to buy a second Nvidia card for my system. I want to know the best card out there for folding. I dont care about power requirements. Highest ppd and least time for WU to complete are my primary concerns.

    Please let me know your suggestions.

    Also whats the effect of GDDR2 and GDDR3 memory, bus width and PCI-e Version (V1 vs V2) on folding performance? The reason I ask is that I added a second GPU that was around: MSI Nvidia 8400GS w 256MB of DDR2 @459MHz Core and 918MHz Shader. Fahmon indicated a PPD of only 500 (Physx disabled)!!
    My current master folder is my XFX 9800GTX Black Edition w 512MB of GDDR3 @760MHz Core and 1900MHz Shader Watercooled with a avg. PPD of 6000-6200 @55-59 Degree C Temps

    Appreciate your help!!

    GTX295, of course. Type of memory, bus width and PCI-E version are of very low importance to folding - GPU's shaders are seeing most use here, so two things are important - number of shader cores and shader clock.
    You should have defined your price range.

    If you have the HW (and funds) to support it yes the GTX295 is by far because of the 2 GPU factor but the most bang for the buck at the moment is the GTX260 216 core.

    I'd actually say a GTX 285 is more your friend. It's more powerful than a single GPU of the GTX 295, which is actually 2 GTX 275s together. The only reason you get more PPD in one GTX 295 is because its got 2 GPUs (GTX 275s) pasted together and you therefore run 2 clients. If you've got space in the computer and funds, I'd get 2 GTX 285s. Mind you if you have the funds you could get 2 GTX 295s and run 4 GPU clients. However that's starting to get really expensive.

    Bang for the buck is definately held by the GTX 260 Core 216.

    Reading your comment it sounds like you just plan on tossing in a card and making it work. If you keep your 9800GTX in the first slot with the additional card in the second, you will run into issues. The second card will run at the same speed as the first and will hamper folding essentially meaning you're folding on a 9800GTX equivalent even if its a GTX 295.

    I believe you can swing for the GTX+ or GTS250 since they have the same chips/similar specs. Gotta get someone else's input on this one.

    You will get error's attempting to fold a 8/9 series with a G200 on the same Mobo, so stick with the GTX+ or the GTS250. Better yet, Newegg has 9800GT's for 79.99 + free shipping. Get 2 of those for the best bang for the buck!!!

    so for folding you need powerful GPU , so 8800 ultra , 9800GX2 , GTX295 this is the best

    If money is no concern the GTX295 is king. The 9800GX2 is an affordable monster folding card. For around $200-220 you can be assured of an excellent PPD/$ ratio.

    You might want to wait for the single PCB GTX295 that is coming...which will probably be easier to LC or add aftermarket aricooling onto.

    Sadly, I dont live in the US and Newegg only ships within US and Cannada. Do u know of anyother online retailers that ship worldwide? Did inquire yesterday about the 9800GTXs ....but all of the local stores here have ran out of stock and some said they dont stock discontinued cards.

    Those 9800GTX's have just been renamed and are sold as GTS 250 nowadays. Actually GTS 250 and 9800GTX+ have the same fully working G92 GPU and the same clock speeds, and the GTX9800 has an older 65nm version of the same G92 GPU. So you can just get a GTS 250 instead of the old GTX9800 that is now out of stock and your cards will happily fold together at nearly the same speed.

    on the cheap end - 9600GSO (DDR3 variant) / 8800GT

    Mid range - 9800GTX+ / GTX 260

    High end - GTX 295
