This will allow you to overclock your CPU higher but at lower voltages. (Although, it's not very necessary if your board does a decent job. Sometimes though if you feel you hit a wall on P67 or Z68 a Z77 upgrade can help)
1600MHz memory is pretty standard now a days. With Sandy Bridge you have the ability to go to 2133MHz. I went from 1600 to 1866 to 2133 and while many people may want you to believe the contrary to what I'm going to say, the truth is I saw a difference in the overall responsiveness, snappiness, as well as program load times of my computer going from 1600MHz to 2133MHz memory. I also saw a distinct increase in minimal and maximum framerates in games. So that's another thing to consider
At this current time I wouldn't consider adding a second 670. It took me a while to reconsider that upgrade path as well. I figured my best course of action would be to sell the 670 for around $300 and buy a GTX 780 or straight up trade my 670 + Cash for a 780. At the moment, we are about to make a move into next generation consoles and although all current released triple A titles proved to be no problem. This upcoming years releases may be a bit different. Which is why grabbing a second 670 might not be the wisest move since every couple of years we make a jump in VRAM requirements eg. 400-500 series nVidia cards to 600 series.
4) CPU Cooler
An H50 with Gentle Typhoons is probably very quiet, however as far as cooling goes it's probably not really that much better than a decent Air Cooler. So if you are going to want to clock above 4.5GHz you would need to get better cooling. At least an H100i. Maybe put on some nicer fans in Push/Pull.
5) CPU overclock
Upgrade your cooling and you can clock beyond 4.5GHz. Not sure what your volts are @ 4.5GHz but I got my 2500k up to 4.9GHz daily after flashing my bios with a beta bios. I thought I was stuck at 4.8GHz daily prior to doing the bios flash. So that is another thing to consider, pushing your overclocks closer to 5GHz daily clock which is quite a satisfying achievement.
Besides that looks like everything is pretty good.
What you're saying would make sense in most cases, but getting his i5 2500k closer to 5ghz really going to make a difference in his games?
I know its pretty well proven that faster memory has minimal impact on gaming performance, and is it going to be worth it? the price of ram has gone up quite a bit. did you go from 8gb 1600mhz to 16gb of faster memory? that can be attributed to your performance increases as well.
Again, his CPU cooler would be dependent on him overclocking more, what is an extra 300 mhz going to gain him with his current system?
GPU, I gotta agree with, 2gb seems to be causing limitations in certain poorly coded games as mentioned above, but for the time being upgrading his current card or adding a 2nd would probably gain him the largest in game performance boost at this point in time, don't you think?Edited by identitycrisis - 8/12/13 at 11:07am
