thanks for the reply. i use a 512mb version of the gts250, and i have an option to trade it for a 1gb version + $10. what you think, trade(and spend a little) or not? What game would take advantage of the 1gb vram in my resolution? GTA4? my processor might be inadequate though..
If i had to choose 1 I would say warhead plays better, then that's just personal opinion but for what its worth it just seemed smoother and the game play seemed to flow a bit better for me. It is quite a short game though so you have to keep that in mind as well. I don't know if it is a different length to Crysis but it seemed like it to me.
The games do a pretty decent job of scanning your system and selecting optimal settings for your hardware. What i would do is download Fraps which is a free download that puts a frame counter in teh corner of the screen. Run fraps with the game and let it select the settings and note your FPS. After that i would notch up the AA until the frame rate gets hit. Crysis and Warhead played best for me at around 35 FPS average. You will soon know if your settings are too high as the first big skirmish will slow things right down if you are trying to use too much AA.
I would guess it will set everything at High to start.
Warhead does run a LOT smoother and easier while looking just as good if not better. Crysis is a piece of crap when it comes to coding and working correctly so it demands 3x more performance then what it actually delivers. As far as gameplay goes I like Warhead a bit more.
As for your settings on that hardware I think you can do high or maybe even very high with no filtering on Crysis. At that low res monitor it shouldn't be to demanding. I would say High would be the best bet though.
