Is it worth it to upgrade my HTPC ?

With the prices of the new C2D 21xx chips and the new DX10 cards being so cheap I was thinking of upgrading my HTPC.

Currently am running:
A64 3400+
Asus K8V SE Deluxe
Radeon 9800 with Accelero Silencer
1Gb Corsair TwinX

How much would I get for these do you reckon? Looking on ebay I thought maybe £45 for the CPU&Board, £45 for the memory and £30 for the Video Card

I then thought about (all with Googlecheckout)
Intel E2160 £48.16
Xpertvision 8500GT £41.75
Corsair 2GB Kit (2x1GB) DDR2 PC2-5300/5400 £47.17
ABit IP95 Socket 775 £24.96
Delivery £20 (individual orders)
Making a grand total of £182.04

What do you think ? Seems ridiculously cheap for an upgrade ?

Have refined it a bit to :

Intel E2160 £53.20 + 4.69 del Ebuyer
Corsair 2GB 5300/540 £47.17 free del Ebuyer
Foxconn G9657MA-8EKRS2H £59.34 + 4.69 del Ebuyer
256MB Asus 8500GT, Silent £62.26 free del Scan
Total £231.35

Still means around £100 for a decent upgrade....
