If I go from 4gb of ram to 24 will there be a significant difference? (haven't bought ram in and while and realized how cheap it is)
I have a 64bit OS too

Perhaps if you have 4 now you'll notice a difference, but it's unlikely that 24 will offer more performance than 8. It's not unlike hard drive space. I'm never going to fill up my 1 terabyte hard drive, so it would be pointless for me to get a 2 terabyte hard drive.

Potentially your system will go faster since your OS is likely gonna use that extra memory to cache application loads. However whether this is going to be enough to have a 'significant difference', I couldn't say.

You simply won't use it for there to be much of a different. You could go to 12 for half the price and still never use the full 12 for general home use, at least. Your processor will prolly bottleneck from the amount of applications you'd have to run before you'd get close to using the RAM.

Or get the 24 and look at http://memory.dataram.com/products-and-services/software/ramdisk

Not all 64bit OS are equal
Maximum memory size on 64bit OSes: Windows 7

Starter: 8GB (don't recall start with 64bit, but that's what that site posted)
Home Basic: 8GB
Home Premium: 16GB
Professional: 192GB
Enterprise: 192GB
Ultimate: 192GB

RRamdisk (not a typo, and get a more recent version) can make use of more than 4GB ram on a 32-bit windows install

32-bit can address up to 64GB physical ram (using PAE paging mode, which is enabled for most people anyhow)
While it's true that the virtual memory space can only take up 4GB ram at most (and 2GB/usermode process at most, but you just create an extra process for extra storage space, just requires a swap when accessing the other 2GB) it can be addresses

As for the videocard 'eating' memory is wrong. The physical memory just gets remapped to the upper 4GB+ region

So:
On a computer with 6 GB RAM and a videocard with 1GB and a 32-bit windows install you can use RRamdisk to create a 3GB ramdisk and still have 3GB RAM left for windows

Doing this of course means you should not use any other tool that accesses the upper 4GB ram on a 32-bit system, because windows does not provide a proper way of sharing that memory between processes (let alone allocate it the normal way)

--
For those who feel like playing with it:
Configure windows to pae mode if it isn't already
use CE and enable kernelmode read/write memory
Go to address 0xc0000008
and write in the physical address you want to map (4kb alignment and may be above the 4GB range) and make the first byte a 67
Then view the memory at 0x1000 and that physical address will be mapped there
