I intend to build a gaming pc. I have already chosen the parts for this pc but I would like to have some second opinion on my choice. I already have a monitor that I can use, I need to purchase everything else. I have never overclocked before and I don't intend to do so now, but I might change my opinion someday. Is the power supply sufficient? Is everything compatible? Are there major bottlenecks? etc.
I'm from Belgium and so I'm not going to use the sites that are often mentioned here, therefore I'm not looking for the best deals and such things as they will very likely not be the same over here, however if you think that some parts can be replaced by alternatives that should be cheaper, please feel free to mention them
.
Lastly, I have two specific questions about his system:
1)I have chosen a Phenom 2 940 processor, if I would take a i7 920, that would cost me about 200 Euro more (including the increased price of the motherboard). Is this worth it? This would also allow me to take 6 gig ram instead of 4 I believe (correct me if I'm wrong). Additionally, is the motherboard only more expensive because of the compatibility with i7 processor or are these motherboards better overall.
2) I can buy a 4870X2 which would cost me 70 euros more than the Nvidia 285 which I have currently selected. Do you think the 4870X2 is worth the extra money?
