Easy Question: This any good for a gaming PC?

OK first of all try upgrading your power supply to 650. Then try getting a hardrive with better rpm's. it will load things a lot faster. i suggest 7200 or up. Also your motherboard can not handle dual cards. I would suggest just buying a better card if you want to use dual because you will not see that much of a performance increase with dual. for cheaper motherboards try using newegg.
