Yes you could flash the earlier 6600 cards before the lazer cutting,and although your 6200 has a 128 bit memory interface,it is still based on the older NV44 chip.The NV40 chip has added features that the NV44 can't support,so flashing your video bios is pointless.The way I see it,you have 2 options.Either overclock it to its max(and hope it lasts awhile),or just purchase a new video card.There are several newer and cheap cards out there that perform much better than the 6200,so upgrading really is the best way to go.If money is an issue,you can get the 3850pro for AGP for a reasonable price these days,or build yourself a new system that utilizes a PCI express slot.Goodluck.
