New Computer build

[Jest]

Hey guys and girls. I've been reading the forums and website for a long time but I just made this account to post this. I want to build my own gaming PC but am not sure what I should do.

I built a $1300 computer last summer for my family to use. I got some pretty good stuff. For my personal computer I am thinking of plundering that PC for parts. Here is what is in it.
Q6600 stock fan and not overclocked
evga nForce 650i ultra mobo
2x1GB OCZ Sli DDR2-800
8800GTS 320MB
OCZ StealthXStream 600w
Antec 900

What I am thinking of doing is taking the processor, motherboard, and graphics card. I do want to upgrade my graphics card. Main question, get a different graphics card now (I am thinking GTX 260) or wait for something new and live with the 8800GTS for now. I am going to be getting a 22-24" monitor at 1680x1050 or 1900x1200.

I am going to upgrade the PSU in order to get something with more amps to for future. Also, I am going to go read some reviews on cases. Have any recommendations on something that has good airflow for overclocking, looks great, and is quiet.

Question: Do I keep the old mobo in the old PC and get a lower end Q2D in it and get a new mobo for the new PC or migrate the old mobo over and get an AMD processor/motherboard in the old PC.

Here is what I am looking at getting so far:
My PC
HDD: Hitachi Deskstar P7K500 500GB
RAM: Corsair XMS2 DHX TWIN2X4096
PSU: Corsair TX750W

Old PC:
MOBO: ASUS M2A-VM mATX AM2
PROC: AMD Athlon 64 X2 5000+

Those 5 things come to $450 before MIRs. My budget right now is around $1000 but might increase so I do have a bit of head room to upgrade the graphics and motherboard.

Thanks for any help you can provide. I am at a cross roads.


EDIT: Thought some of this stuff would be clear from the post, sorry.
Buying in Canada from ncix.com or newegg.ca if it goes official soon. I am trying to spend as little as possible. I have never used ATi or AMD before so am kind of hesitant to go with them.

I thought I posted but I guess I didn't. I am going to (try) to overclock the C2Q.

Read the forums for a long time but not long enough to read the sticky!

Your links don't work, either. When you're fixing them, put a description of the product beside the link, we don't want to have to click through to half a dozen new pages to get a brief overview of what you're buying.

Hard Drive: Western Digital Caviar 640GB, one of the best desktop drives you can buy.
Case recommendation: Antec P182
Graphics: Radeon HD4870
PSU: Seems from the URL of the broken link you're looking at the Corsair 750TX. Not bad.
CPU/motherboard: Why not just swap the AM2 motherboard and CPU you've got with the family's Q6600 and 650i?
RAM: Any 1.8v DDR2-800 will do.

Did you pay for your family's computer originally, or did they? If they paid for it it's not fair for you to pull the processor and motherboard out and replace them with inferior parts. As far as what graphics card to go with, it depends on what games you intend to play. (It also depends on what sorts of gaming your family does or doesn't do.) With a 22-24" monitor I would lean heavily towards getting a new card if you intend to play titles as they come out.

Sorry about the links. I will fix them in a sec. I really want to play Crysis, Warhead, Warhammer Online, and some stuff coming out later. My family doesn't game besides my sister playing The Sims 2. They are fine with me taking the RAM / Processor since it saves them money that they were willing to give me to add to the computer as a gift.

Roguestar, I was going to put the AMD stuff in the family PC and taking the Intel stuff for myself.


I am going to be buying from NCIX.com or tigerdirect.ca but they seem to have worse prices on most stuff. I might wait for newegg.ca to launch because I am sure they will have some awesome opening deals.

Fair enough with the computer swap, then.

How long will it be before newegg.ca are open, though?
