Because of my research I understand that my PSU is low, any suggestions for upgrading it as well would be nice. I don't really have a price range, but I'm curious about low-end to high-end products and the differences. If you know of any great values please let me know!
I'm more so interested to see educated perspective on these issues as opposed to just being told what card would work for me. But I'll take either option!
if you want to play at 1680x1050 resolution, you only need a mid range card between 100-200 at most. a common choice in this would be the Radeon HD 6850, which prices at ~135-150. Though it will require a new power supply.
as for power supply, things to consider are reviews, but if you have a general price range, you can find a psu. the lowest you can spend on a decent quality one would be ~45ish$ for a low wattage model that would work.
Thanks for the informative answers you've given me.
I'm comparing some cards with the URL you provided, but now I'm left wondering what processes a game uses. The benchmark says the 6850 will get 45.7 fps with Crysis Warhead @ 1680x1050 but is the rest of my computer not a factor?
My computer has to be more involved in gaming than just the GPU, right?
I compared my CPU and it said Crysis Warhead @1680x1050 gets 69.8 fps. Is this because Crysis is designed to run on a quad core, to split the tasks, so I can get a max fps of 69.8?
the core 2 quad is okay. if possible a new build may be nice, but it probably wouldn't be 100% required on the resolution you are playing at. but its more or less depending on your budget. it would be more beneficial to start a new build, as fiding upgrades to a ic2quad would be way to expensive.
