When should I buy?

[Mutley]

Currently I have this:
AMD64 3800
1gb DDR 3200 (unbranded)
Nvidia 6600 PCIe
A crap motherboard

I really like the look of the Intel Quadros coming out in November I think, from the success of the Duos, they look mean. I need a new graphics card, I have no idea how far away DX10 is. Need more ram, would really like about 3-4gb ...and a new Motherboard.

So yeh, I need a new PC, just my question is, when should I start buying? And what? Is it worth waiting for a DX10 or get a DX9 card before?

Any reccomendations? Looking for a mid-high budget, £600? For GPU/CPU/RAM/Mobo. No hard-disk or sound cards etc.

If you multitask then look to the multicore CPUs.
If you just run the game and nothing in the background then I'd hold on to what you have a bit longer.

Although a Good gfx card will improve your game a lot more than a CPU update. Not sure if you remember or not but HardOCP benchmarked the Core 2 Duo CPU against the Athlon 64 at high resolutions to remind everyone that things are still GFX bottlenecked. Both CPUs will give you basicly the same framerate at high resolution/detail. Lower the resolution and the better CPU will pull a head. But I don't know anyone with a good sytem that plays at 800x600 rather they play at 1280x1024 or higher with AA/AF. So what I'm saying is upgrade as your budget allows with the GFX as first priority if you have games in mind. You already have PCI-Express so you are free to upgrade the GFX card any time. DX10 would be a good time to do that. If you have money to upgrade the CPU, mobo and RAM then go for it.
