I have an Acer Veriton X4618G SFF that has a slot for a PCI Express 2.0 x1 or x16 card. Anyone know of any decent graphic cards that will fit into this PC for games? I used to play Counter Strike and Day of Defeat back in the days; so just trying to get back into PC online gaming for fun. I know the comp is not ideal for gaming but it is running Win 7 Pro 64bit with an I5-2400 chip and 6gb of DDR3 ram. Any help/ info provided would be appreciated.
