Hi, Please help. I have just started HL2 (wow). My machine is up to the job, but my built in Intel Extreme graphics card just does not do the game justice at all. I obviously need to look at buying a better card, but my problem is its built in so I only have a PCI slot available for the new card. So in short: Which cards should I consider buying? Which of those cards comes in PCI? Thanks very much inadvance. Adict!
