Dude, TRUST ME! Use the Money that your are planning on spending on the Akai to get A GREAT sound card and a FAST Computer. The benefits out ways the Hardware sampler in every aspect.
Remember this..... A good soundcard with low latency means, good audio Quality, high trackcount, and most importantly the ability to run VSTi Softsynths with low latency. These Softsynths have the potential ability to replace our Racks all together. Check out Native Instruments stuff.
Did I mention Plugins? The VST/DX plugins that are available today rock! Checkout the WAVES stuff. Also TC works are really good.
A fast AMD processor and a new Mother Board would be say ($300) for the pair. Spend another few dollars ($100) and load it up with hi quality Ram. Then get a Great soundcard for say $400-$500. That would transform your current computer into an audio powerhouse. Check out RME hammerfall. They make great stuff. Also Echo Audio makes a Great soundcard.
Keep this in mind when designing a PC for audio.
ALWAYS DESIGN THE COMPUTER AROUND THE SPEC's OF THE AUDIO CARD YOU INTEND ON USING.
Personally I'm a Mac user, However I do own and operate a PC to run various tasks in the studio. I use
an Echo audio MONA card with it. When designing my system I basically choose the components (i.e., processor and chipset) for my new computer around ECHO audio's SPEC's. Now let me be clear, I am no PC whiz (in fact just the opposite, I can make a G4 PURRRRRRRR). When you have all your computer parts have a friend put it together or worse case take it to COMP USA or some other kind of computer professional. This will end up costing about $150 to throw it together but well worth it.
All this stuff is basically just preference. One person could like the use of a hardware sampler and a bunch of keyboards, While the other one won't, and prefer doing most of the work in the computer. As far as I'm concerned I use both. Never will I set down my beloved VIRUS or Kurzweil. But on the same tip the EXS24, FM7, and Absynth are all indispensable tools.
Do some research and find out what works best for you. I just thought that you should at least be aware there's another world of music production tools out there.
