hey guys new to the forums i recently upgraded from the pc i made 5 years ago and bought a small form factor hp workstation its got an i3 quad core and 8gb ddr3 so all i need now is a good graphics card. it has a 240w psu so that's something to take into consideration. i have 2 pcie slots and i know it wont fit a normal gpu because i had to take the mount off my nvidia geforce 8400gs just to get it to fit in the case. i was looking at the nvidia gt 640 because im on a budget of under $100. i should also mention that i want to play dayz battlefield 3 record minecraft maybe some need for speed and a couple other light games at medium settings. will the gt 640 do that well? or should i get a different card? if so what card should i get?
