Hi, I know that a 32bit OS can only handle close to 3GB of ram, is there any limit for 64bit OS's?

The emergence of the 64-bit architecture effectively increases the memory ceiling to 2[power of]64 addresses, equivalent to approximately 17.2 billion gigabytes, 16.8 million terabytes, or 16 exabytes of RAM.

Most 64-bit consumer PCs on the market today have an artificial limit on the amount of memory they can recognize, because physical constraints make it highly unlikely that one will need support for the full 16.8 million terabyte capacity

If a 32bit OS only picks up 3.25/5Gb's would applications pick up the full 4Gb's or would it be limmited just like windows?

Some cheaper motherboards only support 4GB RAM. Best to check your manual...
<unless of course it's a decent motherboard>

Nope, apps that work in Windows will only see what windows sees, therefore the 3.5GB.;)

thanks for the advice, now would you reccomend 8GB DDR800 or 4GB DDR3 or more expensive ram?

8GB of DDR2-800 by far! DDR3 is just overpriced for the so called Speed difference.

BTW 8GB's sounds a little overkill :p

+1 on that one.
4GB 800 or even in your case 4GB 1066 (which would cost around R1400 for Corsair DDR2-800 4GB (2x2GB) XMS2 DHX CL4 Memory Module Kit)
is a lot cheaper than
4GB DDR3 800 (Kingston DDR3-1066 4GB (2x2GB) Memory Module Kit @ R7500)

I think 64bit is 128 terrabyte or 1.28 terrabyte or something like that.

I'm running x64 and apps built in 64bit code run quite a bit faster than their 32bit brethren...

x64 FTW !!!!!! :D

Lol you mean 128 Gigabytes of RAM. Definitely not 1.28 Terabytes.
