Pretty solid, even though I think the i5 is a bit expensive for my taste, its definatly worth it, you probably should of bought a 650w it probable would have saved you a little bit of cash, il almost guarantee you can run everything on ultra with that card.
Can someone explain what an ssd does and is a cooler really necessary for OCing? Will the fans with the case not be enuf?
The simplest terms I can explain it - an SSD is a hard drive with no moving parts which drastically increases its' read-write times over a traditional mechanical drive. It will give your system a significant performance boost. The way I'd describe how it works is a bit like a flash memory reader, but that's about as simple as I can get.
As far as the fan goes that's where it gets a bit tricky. Every system is different and will give you different results. The reason I recommend aftermarket fans over the stock fan that's included is that the aftermarket fans are on raised heat sinks which filter the hot air out of the case and keep the cool air recirculating. I'd suggest reading this about air cooling: http://www.tomshardware.com/reviews/cooling-airflow-hea...
Nice setup, though I do agree a SSD and HSF would have been nice additions. Overall though if you've never used a SSD you really just won't know what you're missing so not a big deal. At any point down the road you can always add a Cache SSD that will not require you to reinstall anything, just plug-in and go. The same is true of the HSF, it can be added at any point.
Jsc i did ask beforehand im just picking up on some other comments from other users. Im the kind of guy that walks out of an exam who asks the other students what they answered with the risk of finding out i did shite.
