Pls help me decide!!

All is compatible, I would go with a different psu.

This will cover you if you decide to go SLI:

This OCZ 550w PSU is plenty for a single video card and will save you some $$

The 4890 is better than that gtx 260 for about the same cost

lets say that i stick with the ocz 600w psu, i read on some reviews that ocz can only have 3 sata connections, will it be able to handle all the parts including the thermaltake monitoring temperature? thanks for all the suggestion  

@englandr753
i won't go sli unless someone would give me a gtx260 for xmas   hehehehee

As long as it has the correct power connectors for the video card without having to use adapters I would say yes...

how will i know if it has the correct power connectors? are the adapters bought separately and pls give me the price info.. thanks a lot for the reply  

zakk, I would maybe rethink your GPU choice. The i7 CPU is a beast, and has room to handle a much more powerful graphics card. See today's featured article http://www.tomshardware.com/reviews/build-balanced-plat... for more details on getting a balanced system.

That being said, if you're planning on upgrading to 2xGTX 260s in SLI and a bigger monitor in the future, the i7 would probably be a great choice.

As for power connectors, the GTX260 requires 2 6-pin power connections. It will usually list these requirements in the NewEgg specs, and you can see the connections on some of the pictures (they are on the opposite end of the board as the video outputs). The power supply should also list how many 6-pin PCI-e connections it has. If it doesn't have enough, you can get a 6-pin to Molex adapter for <$3 (Molex is the connection with 4 fat pins, used for fans, disk drives and all kinds of stuff). Some cards even come with these adapters, again check your NewEgg specs or a review of a specific brand's card.

You can use adapters but its not recommended. If you already owned the psu then it would be a consideration but you are selecting a power supply and have a choice to get the right one so an adapter really should be out of the question.

Make sure the psu you are looking at has the correct power connectors, if it doesn't then you need to consider one of our suggestions...

PSUs normally come with an extension cable with additional SATA and molex connectors. Unless you are running a 3-4 drive RAID array with multiple optical drivers, you should have enough connectors.

If you don't have enough power connectors, you can get something like this
