I am planning on building a new system and was wondering about various parts of it.
Memory - Should I get 1GB CAS2 memory or 2GB CAS3? The 2GB memory is about £80 more expensive but I don't know if 1GB is enough? I would be looking to running games and video editing at the same time but my dual core should help to take strain off the memory, no?
MOBO - I am a die hard ATI, and so I would love the new crossfire technology. The problem is that now only Sapphire have crossfire motherboards. Should I wait for someone like Asus or Abit to release a crossfire motherboard or should i stick with sapphire?
graphics card - Again with the crossfire....for it to work do I need to buy a special crossfire card at first, or does only the second card need to be a special crossfire one? Also, ATI have 512MB cards out. Should I go for that with an option of adding another 512 in the future or should i stick to 1 256 now and add another one in the future. Basically I am asking whether having 512 rather than 256 will make an improvement worth the extra £100. Also, in terms of ATI range, should i go for X800/ X850 or X1800?
Case/PSU - I'm not good with this part of the computer and was wondering if this is enough: Antec Black Super Mid Case, Antec TrueControl 550W PSU with 5.25ins drive bay control panel, an extra 120mm internal fan
Other specs are;
Athlon X2 4400+
Creative X-Fi sound card
SATA hard drive with RAID
edit: If I've been to vague let me know
