Some game recommendations please??

I have 512 of ram, and my processor(an AMD Athlon 1700+) runs at 1.4 ghz, and for a video card I have an ATI Radeon 8500. (Kind of an old set up I know, but I workin for a better one, slowly but surely)

Can anyone give me some recommendations for some...

pc games that would run on my pc without lagging horribly?

I've been thinking and I remembered a website that allows you to pick a game from a drop-down menu and it would analyse your computer to see if it was capable of running the game that you chose. http://www.systemreq...

I've never heard of "Wateva" the game; is it good?
