2 12v rails will be a little more stable but most people suggest having 30 or more amps combined or on the one 12v rail. Either 26a should be fine for your rig, I wouldn't use anything under 18a for any computer. I had two single 12v 12a power supply's and they both supply crap for power and fluctuations were terrible.

dual rails split the 12v power for your mobo (cpu, gfx...) and everything else (fans, optical drives...) so that the system runs more stable. If you plan to OC it is often better to have a single rail with lots of amps avalable.

I would not suggest you get a rosewill psu. if you are looking at something that doesn't cost too much get FSP.

for a little more money you can get high quality

Actually the new ATX+12v standard makes dual +12v rails required for a PSU. I am pretty sure on this anyhow. I personally believe that dual +12v rails are a very good thing, my personal favorite dual +12v rail PSU is my own OCZ PowerStream 600W (OCZ600ADJSLI) too bad it costs $209 on newegg!

thanks guys, so basically its more stable and reliable.

Can someone suggest some good PSUs that are fairly well priced (preferably nothing over around 75) so that counts out OCZ

Check out the Antec PSU's on Newegg. I got my 550W dual rail PSU for $80 a while back.
