the killer nic improved my comps from 5% up to 15%. when playing fps games that means i am 5% faster than i was making me better and my shots hitting you first.
I know there are other bottle neck but i just find it funny when people hear omg you running a dual core those are crap when in fact they are far from it and with how programs are made they can only use 2 cores there are few common programs that can use more than 2 (i say common and this is not including the obvious video encoding and 3d rendering)
When someone builds a pc give a look at a dual core and think about your needs, dual cores in most test with average users out preform normal quad cores. yes if your willing to drop 800$ on your cpu alone yes you will beat the duals very much but still at that much money you mine as well go for a dual cpu board and get 2 quad cores and have 8 cores but for the average joe look at dual cores and look at getting 2 hdds one 32gig ssd and 1 250-1tb drive for storage.
i will say ssd are very nice boot drives they can take a bit of work to get their full power but once you got it running you will love the speed increase.
also never go with an off brand psu or memory go for g skill or mushkin.
i found many off brands psu have alot of issues with giving the power they say they will, you will be better going with corsair cooler master and antech then ocz and rosewill. the last 2 i listed i have not had any problems but i know a friend who had to rma 2 of them till he went with a corsair.
also when building stick to above 750watts this is for if you ever want to add 2 gpus or just more hdds you have extra power to spare.
Also if you are cheap i have had good results from the SIGMA MONSTER psu had it running for over 1 year with no issues.
i have built more pc than i can count and when on a budget the duals are good then come the I3 and the I5s. but if you have all the cash in the world go for one of these
