USAGE FROM MOST TO LEAST IMPORTANT: Mid-range gaming. I mostly play slightly older games, and mid-range new games like starcraft 2. I'd like to run games like empire total war and Civilization 5. As you can see, I mostly play strategy games.
CURRENT GPU AND POWER SUPPLY: My gpu just died. It was a Geforce 7350 LE.
My power supply-
300watt, Not sure what all of it means, but this was the rail information on the side of it.
+12Va --- 18A 12Vb --- 18A
+5V --- 13A +5Vstb --- 2A
+3.3V --- 15A -12V --- 0.8A
It also said this stuff:
Power of 12va 12vb total 300W
Max continuous power equal to 350w (not sure what this part meant)
As Your PSU Is Rated For 300W Supply Only At The +12V Rails, The Best Card I Would Suggest Is The 5670/6670. They Come Under A 100$ And Do Not Require A 6 Pin PCI-E Power Connector. Thats The Best For Your PSU.
OtherWise Upgrade The PSU For 40 - 60$, Get Something Like A Corsair/Antec/Gigabyte 500W Which Is 80 Plus Rated, And After That With The Remaining 100 - 140$ Get The ATi 6770!
