Just racked up enough cash to invest in a machine. Done my research but, as it's my first build, I just want to get some advice. I'll be using this machine mostly for physics+engineering simulations and media creation but I want to keep the gaming option open.
The two major concerns that I have are:
1-Does the mobo support SLI? Seems silly but the product website seems to say so, but there's a separate board with SLI designation. What should I get?
2-How's this PSU for my setup and will it accommodate expansion with a 2nd graphics card?
There are two versions of the mother board the regular and the SLI because Nvidia charges a licensing fee. As such I don't think that board does. However you're using an ATI card which uses Xfire not SLI so it's not really an issue. Also that motherboard only has 4 slots for ram so really your maxing out at 6gb with little possibility of upgrade since its triple channel memory.
The WD Black 1TB drive might be worth the few extra dollars.
That power supply should be enough unless you plan to overclock your system (2 4850s need about 425 watts).
Mind you, if you get an ATI card don't bother updating the BIOS since SLI won't be needed anyway. Do download that F5 revision, just in case, but don't install it. Just keep it. I never update the BIOS unless there's a specific bug bothering me and I know it's fixed in the new BIOS.
