I have enough for the 820 from selling my secondary comp. I rarely if ever play games (occasionally I will play a bit of garry's mod) but I do a ton of multitasking (cinema 4d rendering while building UT2k3 maps). Right now I have a 3500+, but I could sell it and the mobo and make enough money to get a decent video card for a Pentium D rig. Should I switch?
