Hi
I want to get doom3 to experience those amazing graphics but know that my
system wont really show it to its full (see system details below).
I'm not really that well informed on PC hardware and wondered if someone
could please advise me.
I'm not sure what motherboard would be in my system, so dont know what extra
ram i could put in it yet.

I also want to purchase a new graphics card, possibly a BFGtech GeForce 6800
Ultra but can someone tell me,
1. would it simply slot into my system or would i need a new motherboard?
Someone told me i'd need a water cooling system!
2. Would it be a waste of money because my processor wouldnt be able to keep
up with the graphics card?!
3. Does anyone know a good online store to order such a graphics card? i'm
in the UK
4. What RAM is the best to buy?
5. Will Half life 2 be better graphics/gameplay?

Also, does anyone know any software online that can tell me exactly whats
inside my PC without me having to open the box?

My system is a Compaq Presario 6540 uk
AMD athlon XP - 2600+ (2.13Ghz)

512mb ddr-sdram

80gb ultra dma hard drive

ATI Radeon 9000

64 mb dedicated video memory

-----------------

The system is about 18 months old

Many thanks for your help
