Yeah, the 650W PSU will provide enough juice for the 5850. For memory, it's best to get 4GB kits.

Get a GTX460 instead of the 5850.. Then get a 4gb kit and a case with good airflow..

im with ATX here. the 460 is pretty cheap and will outperform a 5770 in some areas which is plenty of power.
you definitely need more than 1GB of ram, 2 at the very least but these days you need around 4.
also, not just any case will work, high performance hardware will create a lot of heat, and you need some way to get all of that heat away so the computer wont damage itself so a case with good airflow is a must, usually you cant find a case with good airflow under $60. i would say atleast a cooler master HAF 922 for $89.99 on newegg.com

Yeah the HAF 922 has an incredible airflow, also consider the Cooler Master 690 II Advanced case if you want a case with a more classic design.

1. 460 will ALWAYS outperform 5770 and ALMOST always the 5830 coming neck and neck with 5850.
2. Yes airflow is important but there are some rosewill and raidmax cases that provide decent enough airflow for $30-$40. I got from newegg a rosewill case that has a 120mm fan on the side, 80mm up front, and 80mm in the back combined with the 140mm PSU fan and 80mm GPU fan which makes for plenty of airflow for $18(shellshocker)-usually $35.

I'm 145 $ over the limit of the buget + In Romania, the prices for gtx 460 are exactly the same as 5850 and i pay 200 $ more because we are in a country where noone gives a crap about games. And as i said, I will upgrade it later ( case ,psu , ram) but right now I only have enaugh money for what I said. The question was: "2 gb of ram and a 600 W psu or 1 gb Ram for 650 W psu?" and you pretty much tell me that i have to spend 50 $ more.

Thanks.

2gb of ram and 600W psu then. 650 is unneeded
