"is that because of the monitors or your nvidia card?"
Hehe, I don't know what it is, even hooked up to a G400 something bugs the hell out of me with them, or at least everyone that I have seen to date. I can see the grille and my eyes focus on it which gives the impression to me that it's running at a 60Hz refresh rate, give me headaches in 2D(particularly nasty with anything white). 3D I love the FD Trinis, real sweet(having your straight lines straight is a very nice feature

).
"Serious Sam and Giants, at least. I may also grab MBTR full version, tho I'm not sure. The demo is pretty cool."
Finally got you to get Giants<I hope he likes it or I'll never hear the end of it

>, I think you'll have a lot of fun. Make sure to delete/rename/move the arpfix.gzp file in your Giants/Bin directory(doesn't make a difference for a while in the game). Make sure you watch the cutscenes, several places invented a new award for cutscenes just because Giants are so good. Lots of humor too, along with the eye candy I think you'll enjoy it.
Serious Sam I don't see how you wouldn't like it, it's the closest to Doom updated I've seen yet(far moreso then any Quake ever was). Real simple, kill anything that moves(and a whole lot a sh!t moves).
"Other than SS and Giants, what else should I grab? I like action-type stuff, not RPG or RTS type stuff."
I'm not a real fan of RTSs either, but Sacrifice impressed me a great deal. Nothing like C+C or WarCraft where you are some far aways general type, your down their in the sh!t along with your "troops"(kinda like a Sarge

). I guess the game is supposed to be very difficult(I've heard a lot of people complaining about it, I think games today are overall way the fvck too easy though Sacrifice had a bit of a challenge). Have you given the demo a shot? If not I'd say download it and take it for a whirl. My battle strategy overall is very complex of course, Blitzkrieg, regroup, blitzkrieg again
Other then that, I guess Tribes2 would be a good one. That's more online team based type, but I can't think of any good mindless shooters on the horizon or in the recent past.
I honestly found Evolva to be well worth the $10 I paid for it(though I woulda been p!ssed if I spent $50

). Once you get the hang of evolving your creatures down(which doesn't play well at all in the demo) it is interesting and overall it is a blow things up game(sometimes too much in fact, finding plants to make big explosions, finding keys to open doors for some reason seemed much more intriguing).
No One Lives Forever is an excellent game, but it is very slow paced in many sections and requires you to sneak around quite a bit too much for my tastes(you can kill 'em all in the earlier levels, sometimes you are required not to be even seen or you have to restart). Won a lot of GOTY awards, and it does have a decent challengs to it, but like I said it is a bit slow.
"I don't like to think much while playing, I just wanna blow $hit up."
Well, you might want to think a little bit in Giants. You walk in with guns firing on a lot of the missions and your toast. You can be outnumbered thirty to one or more, a little bit of thinking goes a long way(though you still mainly blow sh!t up

).
