ncix is great, it depends on where you stay. Here in Canada there service are great, ship out in 2days even without fast express, their after service are good too. There are weekly specials, I once save $150 on a gtx 680 after MIR.
And djangoringo is right, getting an ssd will give you more benefit, if you use windows 8, it saves you a heck of booting time, even win7 boot are extremely fast. You will also benefit from faster loading, whereas you can add a ram later on, but if you get an ssd later on, its harder to transfer the os over to the sdd from your original storage if you so wish to do it.
