my AMD OPGA8 (Radeon HD6450) failed (heat sink warped, card non functional) I need to replace the card. I'd like at least the same 1GB and (1) display port and (1) DVI-D (but I'd really like 2gb and at least (2) DP's so I have options on my monitors) 320w PS, i7 win7Pro, 16gb ram rest I can't remember since I can't turn it on... I see a NVIDIA Quadro K2000 that looks like it would do the job, will it work? better option? Thanks, Ben
