Here is my current setup:

Coolermaster Cosmos 1000
PC Power & Cooling 610W Silencer
Gigabyte GA-EX38-DS4
4GB Patriot Viper DDR2-1066
VisionTek 512MB 4870
Intel E8400
2x Seagate Barracuda 7200.10 500GB RAID 0

Here is what I am currently considering buying:
Intel Q9550
Sapphire 4870 1GB to Crossfire with the existing one.

Can my 610W Silencer support BOTH 4870s, overclocked, and the Q9550, overclocked?
If not what is the least-expensive option for a PSU upgrade?

To be honest I'm essentially trying to spend a bit more (<$500 hopefully) on this setup to make it last me another 2-4 years since I'm going to College in August and won't have any money to build a new computer.

Additionally the 610W Silencer only has 2 6-pin PCI-E Connectors, would it be safe to use 2 Molex-6-pin connectors to power the second 4870?

A quick run on the Extreme Power Supply Calculator says that this would be fine, but I would like everyone's opinions on this.

Why the 1gb card since your other one is a 512mb ? the CF will use the "lower end" card to work. So youll have 512mb and the OC speed of the slowest of both.

I would grab 2x1gb card and sell the existing one to be able to use 1gb of video memory with the CF.

PSU can do it but its gona pump ALOT from him. Ill suggest swaping it to a 750W.

You CPU is stil able to handle a CF is you have decent cooling to reach 3.6-3.8 at least . and 4.0 ghz is EZ with E8400.
