The Packard Bell iMedia D3318UK desktop computer?
If it is an iMedia D3318UK model it will have the Part Number - PV.U050Y.019 on the back of the computer tower.
If this is the correct model;
Made by ECS (EliteGroup Computer Systems) for Packard Bell
Packard Bell's name for the motherboard is Denver 10
It's a Micro-ATX form factor. (Size. Should be 9.6 inches by 9.6 inches, or also stated as 244mm by 244mm)
Uses the Nvidia nForce 610i Northbridge chipset
Uses the Nvidia GeForce 7050 Southbridge chipset.
(The Northbridge chipset, and the Southbridge chipset make up the motherboard chipset)

1) Uses the LGA 775 processor socket
The processor socket has the pins, while the processor has the socket holes.
2) Has support for Pentium 4, Celeron, Core2 Duo, and Core2 Quad processors, with up to a 1066MHz Front Side Bus. (FSB)
List of Intel Core2 Microprocessors,http://en.wikipedia.org/wiki/List_of_Intel_Core_2_microprocessors
This way you can look at the processors with a 1066MHz FSB.
I know it will support the Conroe Core, Intel processors, but can't give you factual data at the moment, whether the BIOS program on that motherboard will support Intel's Wolfdale-3M Core processors.
3) Supports (Uses) DDR2 Sdram ram memory at either 533MHz, 667MHz, or 800MHz. (PC2-4300, PC2-5300, and PC2-6400 respectively)
Has two ram memory slots, and will support up to 8GB's of ram memory.
Bear in mind that this is only with a 64bit Operating System.
Otherwise it will support up to 4GB's of ram memory with a 32bit O/S.
(Windows XP Home is a 32bit O/S. Windows XP Pro also, but there is a 64bit version. Vista also comes in a 32bit version, as well as a 64bit version. Never assume all Vista versions are 64 bit.
With a 32 bit O/S, only 3.2 to 3.5GB's of ram memory will be recognized)
4) Has one PCI Express x16 graphics slot.
This graphics slot uses the PCI Express 1.1 technology.
You can use a graphics card based on the PCI Express 2.0 technology.
PCI Express 2.0 is Backward Compatible with PCI Express 1.1
You just will not get the full capability of the PCI Express 2.0 graphics card.
Will you notice?
