I am planning on building a new computer soon. I have been researching some parts online, mostly @ places like New Egg. So far I like the AMD 3700 San Diego and maybe an ASUS SLI mother board. I got a recommendation from a friend to go with something like a 6800 GT or if I can afford it, a 7800 GT video card. I will use the computer for mostly flight simulators. Any thoughts on what parts to use?I Have a very limited budget around 800 dollars. I have already purchased a case and power supply (Antec). I also have a new 250 GB hard drive with a 16 MB cache (Maxtor). Am I going in the right direction? Thanks
