Time to upgrade some components

[Oberon]

Well, the current refurbishment work at my place of work has given me more hours than usual (figure that) so my payslip for this month is a bit more reasonable than usual. Therefore I'm looking to do a spot of upgrading with my CPU, and of course with the CPU I have to upgrade the mobo.

Been looking at a nice little bundle on Amazon that gives me a:
Intel Dual Core E5300 2.6GHz CPU Processor -


Gigabyte GA-G41MT-ES2L Motherboard -


4Gb (2x 2Gb) DDR3 1333MHz Memory Bundle BU001E


For about £132.95.

This is my current spec:

<<< System Summary >>>
> Manufacturer : Hewlett-Packard Company
> Mainboard : Hewleet-Packard Asterope
> Chipset : ATI RS400/RC400/RC410
> Processor : Intel Pentium 4 524 @ 3066MHz
> Physical Memory : 2048MB (2 x 1024 DDR2-SDRAM )
> Video Card : ATI Radeon HD 3600 Series
> Hard Disk : Maxtor 6V160E0 (160GB)
> Hard Disk : Seagate ST3250823AS (250GB)
> DVD-Rom Drive : Toshiba-Samsung CD/DVDW TS-H552D
> Monitor Type : Hewlett Packard HP vs17 - 17 inches
> Network Card : Realtek Semiconductor RTL8139/810x Fast Ethernet Adapter
> Operating System : Microsoft Windows XP Home Edition 5.01.2600 Service Pack 2 (32-bit)
> DirectX : Version 9.0c (May 2010)

I might pay another forty quid and throw a 1TB SATAII HD and SATA power cable and data cable in there as well. After that, I think really it's just a little upgrade on the graphics card front, I'm looking at a HD5570 and mulling it over. It might just do it.

Thoughts?
