Need some upgrade advice

[celliott]

So I have about £200 ish to upgrade my PC. Although I do play games I do quite a lot of multitasking so am pondering whether to go for a cheap upgrade to C2D or go for an 8800GTS or something.

One game I had problem with in particular was Rainbox 6 vegas. Although the first level is known to be a little laggy as they overdid the textures or something, it was unplayable on my system so I left it.

What do you reccomend?

Spec is:

AMD Opteron 170 (Can clock to 2.5GHz but it runs a bit warm, so I run stock)
Asus A8N-E NF4 Motherboard
ATI Radeon X1800XT 256MB
Hiper Type-R 480W PSU (Was made before all the ones that go bang, has been reliable for over 2 years so I have trust in it )
Maxtor Diamondmax21 320GB HDD
NEC 3450 16x DVDRW

Thanks in advance.

Got a Freezer64 Pro at the moment, have reseated it several times with AS5. Airflow in the case is quite good.

I think its the stepping of the chip that makes it run warm. At 2.5GHz your looking at between 52-54c under load on both cores which is too warm really even though it's not going to do any damage.
