I bought my 3xs (i7, 2.93 GHz, 3GB RAM) for home recording but would like to play the odd game or two on it also, Call of Duty-type. I'm not a die-hard gamer and know zero about graphics cards, so would like a non-technical recommendation for a good graphics card that will be compatible with my 3xs and make games run smoothly etc. Budget - not a problem (within reason). Thanks.
