Alright everyone, I have a couple of simple questions.

I currently have this rig: (gaming, some video editing, homework, surfing some)

Antec 900
E8400
MSI P7N Diamond (780i)
8800 GTS g92
WD 640 GB HDD
OCZ 700w GameXtreme PSU
2x2GB Crucial RAM 4-4-4-12
Vista Ultimate x64 (got it cheap)

I was trying to figure out if I should upgrade.

I have 2 22" monitors. I know the new drivers will allow me to SLI and use multiple monitors.

My question is: Should I get another 8800 GTS for something like $140? Should I get something else? Will the new drivers let me mismatch the GPUs and still SLI or not?

If I do upgrade the GPU, should I get a PC Power and Cooling 750w - only $80 after rebate.

Somewhere down the line - Future upgrade: 9550 - is it worth it over the current E8400 - I don't think it will be too significant.

I appreciate any opinions that anyone has about my possible upgrades, I would appreciate it.

I have an aftermarket cooler for the E8400 and wanted to push it to 3.6 - just haven't had too much time to mess with it - would like to make sure I do it right.

I would get a GTX 260 (216) if I was sure that I could use both GPUs. Do you know if I can mix and match in SLI like was promised months back when the Big Bang II (180 drivers) were rumored?

If I can mix and match, I think I might get one. The other issue is that my PSU has 2 6-pin connectors, and I know I would need more if I were to get a newer GPU.

That's why I was wondering if I should get the PC Power & Cooling PSU for only $80.

Thanks for the reply Proximon. I appreciate it.

Thanks Proximon. That's a pretty big jump for me, plus it will help since the second monitor obviously uses some of the GPU power.

At only $140, it seems like a pretty decent upgrade.

Any thoughts on whether I should get the PSU - PC Power & Cooling 750w?

Also, what's a good GPU that doesn't need a PCI power connector to possibly use later as PhysX card? 8600 GT? (most of the newer ones require the extra power)

Cool. Thanks.

I'm just trying to figure out if I really need to upgrade my PSU for the OCZ GameXtreme 700w or not - I guess there's nothing lost if I give it a try still. If it doesn't work, I can always buy a different one.

Thanks for the help.
