the 6200 series are very good for the price, however they are still the lowest end of the gefore 6x range.
For example a 256mb geforce 6800 Ultra has 16 pixel processors, 6 vertex prcessors, 256-bit bus width, GDDR3 memory, 400Mhz GPU and 1100Mhz Ram speed.
A 256Mb 6200 geforece 6200 however only has 4 pixel processors, 3 vertex processors, 64/128-bit Bus Width, GDDR memory, 300Mhz GPU and 275(550) Ram speed.
What does all that mean? Well the 6200 is a good budget card that will do everything you need, all direct x 9 effects, shader 3.0 etc, just not with as high a fps rate as a higher spec card in the same range. Does this acually matter? Well, I've played Doom 3 and HL2 perfectly smoothly at high detail on a 6200, so not really, unless you wanmt to show off when benchmarking
