I am trying to evaluate these two boards -- EVGA 01G-P3-N988-TR GeForce 9800 GT Video Card - 1024MB DDR3, PCI Express 2.0, DVI, HDMI, VGA and the GIGABYTE GV-N520OC-1GI GeForce GT 520 (Fermi) 1GB 64-bit DDR3 PCI Express 2.0 x16 HDCP Ready Low Profile Ready Video Card. The 9800 board has 120 streams and the 520 has 40 while the 9800 core clocks at 550 while the 520 core clocks at 550. The memory clock on both boards is 1800 and the shadder clock is 1375 for both boards.
Which would you buy? Both boards are about $50 after rebates, etc. Is there any better boards in this price range.
Quite frankly, the GT520 is a piece of crap. The thing you need to question is whether or not the power supply in your system will run the 9800GT, as it is a power hog. Clocks and memory don't really matter unless it is an insane amount.
Think of it this way. A Honda Civic has about 140hp, and a Toyota Corolla has about 140hp. In a hypothetical situation, the Civic weighs about 1000 pounds less, who's going to win the race?
Its all about the GPU on the board.
What power supply do you have? Will it run the 9800GT?
