Rate This Laptop 2+2

[GoldenIP]

I have just played around with customising a laptop on DELL. These are the main components:

<font color="red"> Intel Core™ Dual Core Processor T2080 (1.73 GHz, 1 MB L2 cache, 533 MHz FSB)
Genuine Windows Vista™ Home Premium - English
Collect &amp; Return, 1 Year Service only
15.4" Wide Screen WXGA (1280 x 800) Display
1024MB 533MHz Dual Channel DDR2 SDRAM (2x512)
80GB (7200rpm) SATA Hard Drive
Intel® Media Accelerator 950 Graphics Up to 256MB shared graphics memory
Fixed Internal 8X DVD+/-RW Drive including software
9 cell Lithium-Ion Battery (85 Whr) </font>

It came to ~£525 (~$1,000)

All I'm going to be using it for is the following:
Microsoft Office
Multi-tabling (4-6 tables)
PT &amp; PAHUD (obviously running in conjunction with poker tables
MSN Messenger
Web Browsing (Firefox)

Basically, nothing out of the ordinary or anything such as hardware draining games like Oblivion and FEAR.

Is this laptop suffice?

Do you recommend any worthwhile upgrades i.e. CPU power, graphics cards etc? Basically, if I upgrade, I want it to be money well spent.

Thanks!
