I can see some experts here and i really need their advice...guys..actually.. I'm not a very big gamer, but i do love gaming...my current pc specs are core 2 duo E4500 2.2ghz processor, 2.5 GB DDR2 RAM, Geforce 210 1G/D3 and windows 7 32-bit, and i can get around 30 fps for games like resident evil 5 and remember me on med settings....so...will upgrades like 4 GB DDR2 RAM with core 2 duo E8500 3.16 GHz give me decent gaming experience on med settings and if yes, then should i go for windows 7 32-bit or 64-bit or maybe windows XP service pack 3 because of low RAM?? plz help guys....thanks......
