i have an older computer, and was wondering if it would be worth upgrading to play current games like minecraft, wow, or black ops 2. the info........ it has a P4Dual-915GL asrock motherboard. the ram is 512mb. the graphics card is a geforce fx5200. power supply says max 385 watt. it would be nice to know a basic total price on the upgrade and if it would be worth it. i also have a left over gt520 graphics card from my newer computer, do you think it will work with the asrock? i know power supply and ram must be upgraded. thanks!
