Hi there my laptop is an Acer Aspire 5920G, mine has an Intel Core 2 Duo T8100 2.10 Ghz processor, an ATI Mobility Raedon HD 3470, and a 3 GB RAM Memory, the RAM and the processor can handle any game, when it comes to minimum requirements, for example minimum requirements Battlefield 3 and Medal of Honor Warfighter both can handle the minimum requirements of both of these games but my GPU screws everything up! That weak piece of crap can't even handle games from 2005 at their maximum! So I wondered if I can upgrade it at all? And if so I would like to change mine for an ATI Mobility Raedon HD 3800 series, or any other that is just as good
