Using a RAM drive to speed it up?

Do you think this would increase performance dramatically with R4? Basically making this the main hard drive in the machine with basically a stripped down copy of windows and r4 running. Should be plenty of space with 4 gigs on it (the RAM DRIVE)
Gigabyte I-RAM DDR PCI Virtual RAM Disk SATA W/ Backup Battery
hrough GIGABYTE's custom intelligent controller, i-RAM acts like a regular SATA hard drive at theoretically 1.5Gb/s data transfer rate. By utilizing conventional DDR memory modules, i-RAM is outfitted with four 184-pin DIMM slots that will accept any DDR DIMM and support up to 4GB unbuffered / non-ECC memory. Most of all, the major issue of data lost after powering down is solved by i-RAM's backup battery which is charged by your system on the fly. Without mechanical elements of traditional hard disks, i-RAM's stunning performance coming from the nature of DRAM as storage medium benefits in massive storage access application such as video / audio capture & editing and 3D graphics design applications. i-RAM is the fastest storage device you have ever imagined !
