Hey fellow Techies! So I'm almost new to modding and building computers (in fact I have never baught one or built one in my life - I'm 13) but I got a lot of money saved up and am getting more and it's so much more worth spending 600 on a computer than on a PS3 unless you aleady have one. .. Alright to the point... I am researching hardware on Newegg.com, Directron.com, TigerDirect.com, and Geeks.com, all of which provide great discounted prices (Although TigerDirect can be a bit pricy) But I'm getting the sense that its much more easy and hastle-free if I buy one from a Desktop Configurator Retailer (I'm looking at CyberPowerPC.com, God that's a great site -- But if aanyone else knows a good site that's cool) -- It tells me I can install two seperate graphics card and I don't know whether that means they have to be the same ones or different. Do they run at differnt times or at the same time? The specific graphics card I'm thinking of (On CyberPowerPC) is the nVidia GeForce 8500 GT 512/256 mB 16x PCI. Because this question doesn't have anything to do with the horrible Dell I'm posting this on, I'll put the specs of what I'm looking at: CPU - AMD Athlon 64 X2 4400 or 4200+ Dual Core CPU Mobo - GigaByte GA-M55SLI-S4 nForce4 SLI Chipset DDR2/800 SATA or Asus M2A-MVP AMD 480X Crossfire Chipset DDR800 Dual PCIE SATA Memory - (x2) 512mB Corsair DDR2 or (x1) 1GB Hard Drive - 200GB or 250 GB SATA-II 3.0Gb/s 8MB Cache 7200RPM HDD Yes could anyone please help explain this to me and/or suggest which of these compnents would be fit the tight 620$ minus monitor budget and the fact that I only need this for entry-range gaming and word processing (My parents probably would let me spend all my money on something to game on) One LAST thing could someone tell me exactly wat a modem is and why I should spend 14$ on it?
