If your computer can run any games without lagging, what's the best PFS?

i just reinstall cs original in my computer today since my friend asked me to play with him. after 4 yrs of not touching it, and its graphics look like a piece of **** now, it's so painful to watch its crappy graphics. Here is my argument with him, I think most ppl who still play cs now because their computer cannot run current high hardware demand FPS games, so they have to stick on cs. I admit it has many cs users online, but come on if stalker, rainbow six and b2 2142 have so many players online, they will be much funner than cs.

Another of my argument is that if people can play any FPS games on their computer, they wouldnt want to play crap graphics games like cs.

Counter Strike: Source at 78 and any other source game basically anything else i cant really play nor do i have money to try anything else lolzors
