Need advice on System Upgrade for PS2

[JoCool]

Hi,

I'm planning on upgrading my system for the release of PS2. I'm a poor university student and to make things worse, married, so the funds are low. I plan on spending €200 in the first round.
What I'm aiming for is to upgrade in serial steps, getting a performance boost first, then eliminating the created bottleneck second.

My system specs are:

Intel Core 2 Duo E6600 @ 2.40ghz with 4096KB L2 cache
MicroStar P43-51 Mainboard, S-ATA2, x16 PCIe, 4x Ram
2x 2.00GB of DDR3 (PC3-8500F running at 533MHz, can it go to ~609MHz?), 2 free memory slots on MB
NVIDIA Geforce GTS 250 1.00GB, clocks: Core 702MHz, shader 1502MHz, memory 1000MHz
HDD Western Digital C WD5000AAKS (blue)
Monitor is a Samsung 19" 4:3


I will upgrade the monitor to a 24" HD for 1080p and I'd like to improve FPS on that resolution as well as the texture quality I can use. Therefore I think about buying a graphics card of up to €160 and buy 2x4GB of faster bus memory for €40, to pair it with the older 533MHz.
In spring I would then go for a new board with a new CPU and replace the old 2x2GB DDR3.

My knowledge about today's systems is almost non-existent so I ask you for help and advise on if my general direction is right and what products I should go for (so that a consecutive updates will not be denied).

Best regards!

I can sell you my 460 SE's for under 160. If that interests you. The 460 SE SLI is I believe right around or under a single 580, which should do you fine I think.

Very nice of you but I don't know if my current board supports SLI, I don't think so.

I'm also looking for advice on what types of models to buy, which ones are the most cost effective for PS2.
