ok ra imo purchase bro, at least its better than your current 8400GS 64-bit... although pwede unta ka add gamay and get a better performing card puslan man nilapas ka sa imo budget na php3K...
anyways im contented with my HD 4650 DDR3 even if this is lower than your GT220. jst dont expect so much from this if imo i enable tanan high-quality settings sa games(depende hinuon sa games)
dont worry too much. i salpak na deretso and enjoy your purchase....
PS
let me remind lang that vram/memory capacity sa videocard has little or less influence on the overall performance sa videocard. the kind of gpu and memory used(DDR3 or higher) are only 2 of the things that influences videocard performance. btw, get a decent powersupply.
post lang if need help...
