I'm looking to buy a graphics card for my pc. My current one is rubbish! First of all, will any graphics card work ok? Or does it need to be a particular configuration to suit my PC? What are the things I need to see if they are compatible with my PC when looking for a graphics card? Secondly, is there any difference between a graphics adapter and graphics card? Thirdly, I've shortlisted these graphic cards/adapters. Which is the one I should go for? I'm looking for one that basically lets me play the latest games at high FPS. Thanks! http://www.amazon.co.uk/Inno3D-GeForce-7600GS-512MB-Graphics/dp/B000M2WL62/ref=sr_1_1/026-0516226-3522044?ie=UTF8&s=electronics&qid=1181987817&sr=1-1 http://www.amazon.co.uk/Sapphire-Radeon-x1550-512mb-11093-10-20R/dp/B000N0OMDS/ref=sr_1_6/026-0516226-3522044?ie=UTF8&s=electronics&qid=1181987817&sr=1-6 http://www.amazon.co.uk/Sapphire-Radeon-X1650-512MB-Graphics/dp/B000RF4CDO/ref=sr_1_15/026-0516226-3522044?ie=UTF8&s=electronics&qid=1181987817&sr=1-15 http://www.amazon.co.uk/Inno3D-Geforce-8500GT-800MHz-Graphics/dp/B000Q2LRYA/ref=sr_1_16/026-0516226-3522044?ie=UTF8&s=electronics&qid=1181987817&sr=1-16 My CPU configuration is: # Intel Pentium 4 517 Processor # 2.93GHz, 533MHz FSB # 1024MB DDR RAM # 80GB Hard Disk Drive # Multi-Format Dual Layer DVD RW Drive # 256MB ATI Express X200 Graphics # 2 USB Connections # 2 PCI Slots # Microsoft Works 8.0 # Microsoft Windows XP Home Edition So has it got the PCI thing?
