This is what always puts me off pc gaming:
It's cyber Monday, lets see if I can get a good deal on a gpu upgrade. Turns out most cards still need more then a 350 watt power supply, ok I can replace that. Crap I also need two PCI-E slots next to each other or it won't fit. I'm not going to replace the motherboard, forget it.
So lets check out the Geforce 640, 1 slot, 350 watt, looks perfect. Or not:

Bad performance compared to the HD 7750, barely maintaining 30fps at 1080p. The 7750 doesn't fit in my system, and I can already get 1080p30 with my current 3 year old card.
Goes back to play AC3 on ps3.
