i would like to know what a good upgrade ( or even if it is worth upgrading , i use my pc for gaming ( and yes , i can game on this pc))would be from my evga gt 710 2gb ddr3 . i have a core two quad q8400 . i would mostly want to upgrade the GPU but if there is another socket 775 CPU that would offer a noticeable improvement i would be willing to buy it if it is in my budget . my pc is an upgraded optiplex 780 mt and has the 305 watt psu it came with . i have 1 hdd , 8gb ram ( 4 sticks ) 1 dvd rom , 1 dvd rw . 1 storage card reader , usb mouse keyboard and headset ( mouse and headset are LED , i dont know if periferals change power required ) and i plan on adding a wifi card . thank you for reading .
