Hello Experts...

I'm little confused while upgrading my DELL XPS 700 desktop PC. I'm however using the instant RIG with following specifications:

1. nVidia nForce 590 SLI Intel based Motherboard
2. Intel Core 2 Duo Processor E6600 2.40 GHz 4M L2 Cache
3. 4GB of DDR2 RAM
4. 4 x 250 SATA Hard Disk Drives
5. nVidia GeForce 7950 GX2 dual graphic adapter
6. Creative X-Fi Extreme Music sound card

I understand that we may transform the above referred processor i.e. E6600 into Intel Core 2 Extreme Processor X6800.

But at the same time, whether we're in a position to change / convert the instant processor into:

A. Intel Core 2 Duo Processor E6850;
B. Intel Core 2 Quad Processor Q6600; and finally
C. Intel Core 2 Extreme (Quad) Processor QX6800

I've no idea whether nVidia's nForce 590 SLI Intel Edition is fully compatible / supportable with above referred processors?

Awaiting your technical suggestions / recommendations...

Regards,


Max
