Greetings!
Since my Recent Post about my little IBM thinkcenter 8810 post i wanted to upgrade the CPU as well as the RAM. I was already suggested a top of the line CPU and for a great price too. Im still debating on it. My current setup is this:

Core 2 Duo 4300 1.8Ghz
3gb Ram
160gb Maxtor Main SATA
200Gb Samsung Secondary SATA
Geforce 310 by Pegatron (512mb Gddr2 PCI-e)
Windows 7 Home Premium

I was suggested this Chip that has double the Cache: http://www.ebay.com/itm/121445990490?ssPageName=STRK%3AMEBIDX%3AIT&fromMakeTrack=true

But what i want to do is possibly double the RAM on this little to be Beast. It currently has 3Gb (512mbX2+2x1Gb=3gb)But Also whats this Pc 5400 and 333mhz mean?there is different kinda on ebay.  So i was wondering with Retail value of a 2gb stick is around $50 is it worth it and trusted that i get something like this: http://www.ebay.ca/itm/New-4GB-2x-2GB-PC2-6400-DDR2-800-800-Mhz-240-pin-DIMM-Memory-For-AMD-CPU-Chipset-/151342735977?pt=US_Memory_RAM_&hash=item233cbae269

Basically i need this machine for school and as im using it to capture some video, web surfing and some word processing, and MINOR GAMING from time to time. You will need a 64 bit ver. of Windows to take advantage of that extra RAM...
