|I'm curious why you went with an old LGA775 setup rather than going with the a Core-i3/5/7 CPU & board? Here's your motherboard specs:|
I'm also curious why you bought 2GB RAM? The board you chose only has 2 memory slots so to be able to run dual channel mode, you will have to add another matching 2GB stick. What you should have done was buy an 8GB (2 x 4GB) dual channel kit.
"One more thing, FSB for mobo is 800/1033/1333 and RAM is also having 1333 MHz frequency"
None of those are frequencies, they are QDR & DDR speeds. 1333MHz FSB CPUs run at 333MHz frequency. DDR3-1333 RAM runs at 667MHz frequency. Whether you get a dual-core or quad-core CPU is up to you. It depends on what your primary use will be & how much you're willing to spend. You certainly don't need a quad if all you're going to do is surf the internet & send emails. And if you plan on playing games, you'll need to add a PCI-e video card because the integrated GMA X4500 isn't going to cut it. Here's the CPU support list:
Whatever you do, make sure you invest in a decent brand name power supply (Antec, Corsair, Seasonic, etc), not a crappy VIP, iBall, or no-name generic unit. Do you plan on overclocking or will you just be running everything at it's default settings?
