the 9800GT for $99 is not a bad deal. of course you could get a 4850 for that but he would then need a better PSU. meaning then he would be spending more than just $99.
Is the 4850 a huge jump over the 9800 GT? I'm not trying to max anything out @ 1680x1050 just make it look best at a lower resolution
If the performance difference is huge I'll try and get the 145 dollar set up if it's not I guess the 9800 GT? I've read even the 4830 beats the 9800 GT
the 4830 and 9800GT are really about equal. but the 4850 is a good bit faster. it couldnt hurt to get the 4850 and better PSU especially if you plan on upgrading your rig in the future.
