Ok, so I want to upgrade my videocard(s). Normally this wouldn't be a problem but I'm low on expansion slots and with all the stuff coming out I could use some advice. Current specs: cpu:amd fx-62 ram: 4gb OCZ 900mhz ddr2 mobo: asus crosshair SLI 590 HDD's: 5x500GB in raid 5 array - 1x 500GB system disk soundcard: creative Xtreme gamer Xfi Videocards: XFX 8400GS (its a placeholder) and Radeon 7000 (to drive extra monitors - I had some old CRT's laying around) Now ive got a pretty (~1000$, but I want to get an AMD quad core later) flexible budget, but the expansion slots are a problem. my mobo has these slots, in this order: --------TOP--------- PCI slot PCIe x16 slot PCIe x4 slot PCI slot PCIe x16 slot PCI slot ------BOTTOM------- and the cards I currently have are: Radeon 7000 (PCI) Geforce 8400 GS (PCIe x16 - Single slot cooler) creative X-fi Xtreme gamer (PCI) Highpoint RocketRaid2220 (PCI) Also, I want to get another Rocketraid 2220 at some point. And if things weren't complicated enough: I want to keep my extra monitors - that mean IF i go sli, I need an ATI card to drive my extra monitors. If I get one card (for my main monitor) I could use my 8400GS to run the extra monitors. I am considering SLI 8800GT's, but these dont have DX10.1 or SM 4.1 support, I know ATI's cards coming out soon do, but I am unclear on how big a deal this is. SO there you have it. Possibly one of the most complicated upgrade decisions I have had to make. PS: I am willing to get a PCIe 1x ATI videocard for my extra monitors (~100$ on newegg). I may also be willing to go crossfire if there is a good reason to. I know this is really long and complicated and if your still with me and know whats going on - Thank you - I need the advice.
