I'm thinking of getting a gigabyte iram and 4GB DDR

[Onceler]

or is the iram2 going to be released soon
any users with experience with the iram?

It's not a bad idea. I have done the same and it helps when you are in situations where your system is thrashing the HDs due to page file activity. Depending on your usages and your OS, you may be better off adding system memory.

Google for Acard 9010 or 9010b.

9010 - professional grade - $400
8 DDR2 slots for up to 64GB (with 8GB ECC sticks)
Dual SATA ports for single-drive Raid0 function (increased bandwidth)

9010b - consumer grade - $250
6 DDR2 slots for up to 48GB
Single SATA port

Both feature battery to maintain data integrity in event of unscheduled power failure and have a compact flash slot to backup data before reboots/shutdowns.

Or you could just add more memory to your motherboard and configure a ramdisk. SuperSpeed has a software package that will let you enable a 4GB ramdisk on XP32 so you can keep 4GB system RAM and also have 4GB ramdisk for swapfile or Photoshop scratch disk.
