If you won't a gaming computer then your looking at about $200+ for a good GPU+PSU.
You mean, if he's not a gamer? Because if he is, then he'd need to spend a lot more on his GPU.
Your not going to be able to get much at all with your current power supply even a 9800GT would require a new power supply. The best thing you can do is give is a budget and tell us what you will be using your computer for. If you won't a gaming computer then your looking at about $200+ for a good GPU+PSU.
Well i have been playing games like rome total war which work well on this computer with 512mb gpu but id like to upgrade for some heavy gaming in the future.
The power supply will be upgrade as i get closer to my final decisions, would a 500 watt power supply do the job.
Thanks
So would it be any point in upgrading the gpu from a gigabyte geforce 8600 gt at the momen.Well the memory of a gpu has little to do with it performance. A 10GB 9600GTX still would be nothing compared to a 512MB 4870. A 500w psu will work depending on what card you get anything like a 4870 would require a 600w or better remember it better to have more power the less.You said you wanted to upgrade so you can do some heavy gaming in the future for that a 4890 would be the best.

Also how do u jusify the performance if its not the momery of the gpu.
Of course it's a good Idea to upgrade the 8600GT but only if you plan on getting something like a 9800GTX,4850 or your not going to see much of a improvement. The best way to compare a cards performance is by benchmarks of course http://www.tomshardware.com/charts/...ity/3DMark06-v1.1.0-HDR-SM3.0-Score,1339.html.
The 1GB 9800GT Gigabyte is good and has a higher point win over the Radeon HD 4850 Video Card. Which is good for gaming.
So a 600 watt psu would be the minimum required
