I'm a bit paranoid about all this stuff.
Anyway I'm planning to buy a Geforce GTX460 card (either 768 or 1024 mb ram, havent decided yet) by Gainward or Gigabyte (I would get MSI cyclon but its not available in my country yet). Anyway Nvidia recommend at least 450Watt power supply, while I got 430W Seasonic S12 II Bronze.
The rest of the system is:
Intel Core I3 530 2.9Ghz
Kingston DDR3 2048MB 1333Mhz (x2)
Samsung HD502HJ 500MB
I assume this is the unit in question; http://www.newegg.com/Product/Product.aspx?Item=N82E168...
it isn't optimal but Seasonic is a good brand and it should handle that card and system fine. Giving a large OC to the card and processor and running stress testing software is a bad idea but beyond that it should be alright.
The question also, is there something else that need amps on 12V rail on my system, cause there might be not enough amps to all (I dont remember physics very well, so dont remember if amps get divided).
Don't worry about the overclock but I also wouldn't spend more for it. You can OC on your own very easily and achieve much better results.
Those Gigabyte cards are pretty decent but I would recommend an Asus DirectCU or MSI Cyclone instead. They have the best cooling.
jyjjy, wa1 Thanks, Ill get the regular 768MB ram
About Asus DirectCU or MSI Cyclone, none of them yet available in my country, so I either can order from outside the country or wait when they will be here.
