There's no such thing as a terabyte of RAM, and I have never seen any videocard with 2GB of video memory.
Since your motherboard is probably from an outdated company too, I'd suggest just getting a new computer.
If you want to custom-build your own, I'd suggest contacting Reactor Worker with an approximate budget.
If you just want to buy a pre-built, again I suggest contacting Reactor Worker with an approximate budget.
Please, PLEASE, tell him your budget and what you will be using the computer for often.
Example as such:
Hi,
I want a new computer.
I have about $2,000 to spend, and I'm looking for a pre-built computer.
I'm probably going to use this computer often for playing Blockland and school work, maybe movie playing too.
