No problem. Like I said that box will work you just need to have patience while it does it's thing. Yes, max out the ram, that will help some but still, it will be sloooow...my machine is a mid range PC (Geekbench 7K vs 12K) and I can render 6 or 7 RT's in about 8-10 seconds depending on the tune. It cost me $600 to have it custom made almost 3 years ago. A decent i7 will be at least twice that depending.

I also completely understand some folks are strapped for cash so in your situation if $400-600 is big bucks for a computer that will further your music, so be it. Still, I like to use other worthwhile hobby's people get into for comparison, how much do folks spend on boating, going out to dinner and a movie, camping, model airplanes, golf, woodworking, anything? It's usually a heckuvalot more than a hundred bucks for a PC and a few hundred for some software. Realistically to set up a little PC based home studio that you will be happy with including a decent monitoring system will start at $1,500 and the sky's the limit from there. There's people on this forum that have 10k sitting in their bedroom. A really good studio monitoring system is 2-3K by itself.

To clarify one point you might be missing, RB is slower than Biab because it's not Biab. It's a completely separate program that is based on Power Tracks Pro Audio. PT has been PG's in house DAW for years now. Somebody got the brilliant idea to somehow graft some Biab functions into it and it's killer but still, it's not Biab but it also does things Biab can't. It's pretty decent, great for noob's because it's relatively easy to learn but it's not Sonar or Cubase either but then those programs cost more than a $400 computer and they can't generate Biab tracks. Once you figure all this out you'll realize you can get your best results by using both programs.

Seriously though, plan on donating that PC sometime in the future.
