Well, I made this computer about three months ago. So far everything is running perfectly. I'm thinking about upgrading it a bit by adding a new videocard and another 1TB hard drive.
1. My motherboard (Gigabyte EP45-UD3P) has two PCI E 2.0 slots, but if I were to crossfire, they would only be running x8 x8. Is there any real disadvantage to having the cards run x8 x8? Will I still see an increase in performance?
2. My CPU is only a C2Duo E7400 OCd to 3.3ghz, will my CPU be a huge bottleneck if I decide to get another 4870?
And if your e7400 was a bottleneck, what would you do?
It won't matter. You'll still play games fine. Although you should technically be able to extract a *lot* more performance out of that e7400. HIT 4ghz xD!
Edit: I realized I wasn't being very clear. The e7400 will certainly bottleneck that 4870 CF, but that's because its just monster graphic-crunching power, and it's really not a life-threatening bottleneck.
I'm not a master of overclocking, so i'd have to read up a bit more on hitting the correct voltages/clocks etc etc. I have a Coolermaster HAF932 case with a Coolermaster V8 CPU cooler, and my temps are usually good (i've seen max like 42c with a full load).
Do you think it would be worth it to get another 4870?
