So basically, I want to get back into folding but don't want to deal with the hassle of not being able to use my computer for browsing or gaming because f@h is running. I will be buying a new graphics card specifically for that purpose, and I want it to be under a budget of $100. I also don't want astronomical power consumption because electricity here costs ~4x higher than in the US. Since I'm going for bang-for-buck, buying used is completely okay. I was browsing on eBay and I saw that I can pick up for under $80 a GTX 460 768MB, a GTX 465 (unlockable to GTX 470), or a GeForce 9800GX2. Which one of those would you guys recommend on a performance/dollar and performance/watt basis?
