I see a lot of people talk bad about the 6200 video card.. and I really can't complain about mine.
I paid $40 for it (AGP)... kept it for my upgrade.
I have an E6300 conroe, 2 gigs DDR2, and the 6200 video card. I get 40-50fps consistently at 512 texts, 1280X1024, and sliders about 2/3 to max. I used the hi-res pack at 1024 texts for awhile and framerates still in the 30-40 range, but went back to 512 after occasional stutters developed. I get a constant 75FPS at 256 texts, but don't care for the appearance at that level.
The only video problem I run into is flames and heavy fog. Gets real jumpy in those conditions, especially when zoomed in.. but still playable.
Yes I'd love to be able to max everything out, but I just don't have the money to invest right now. While my M/B does support PCI-e, I'll probably replace it anyway when I choose to upgrade to PCI-e, as it only supports 4X. I'll probably get a high end AGP card before that happens though. Also a new power supply at that time.. I only have a 300watt (Haven't checked amperage ratings on it.. but no problems). I put new guts in my old Systemax case... but that's all down the road.
I'd imagine though 1680X1050 might be a bit much for this card.. without dropping down to 256 texts... so good luck with your new card
