I just recently got back into gaming, consequently I needed a rig that could do it. This is what I picked out what do you think, be brutal. It took a lot of time for me to sift through the many parts out there and there is probably a reason why I went with what I did.
Ivy Bridge I5=I got this chip when Ivy was just coming out, I didn't know that it didn't overclock as well as sandy (you never know until you try). It still does everything I ask it too and I haven't even gotten to overclock yet.
CPU Cooler= I wound up with the Noctua NH-D14, I haven't tried much overclocking yet but currently I'm at 4.2 with a little bump in voltage ( I forget exact) and temps are really good.
Motherboard= Holy wow did this take a bit to pick out. This Asrock board is exactly what I needed. The dual pci express slots gives me the possibility of going sli in the future. It has the right USB, esata, ect... for my needs, and at $135 its a steal for what it all does.
Memory= I went with the g.skill because it did have good reviews, there were very few complaints about incompatibility. I haven't had any issues with it so far.
Storage = I went with Crucial M4 because there were very few reviews stating they had stability issues. It is a very fast and reliable.
Video Card= I just upgraded to the gtx 780, I know its overkill for 1080p gaming, but it was meant for a bit of future proofing. I really want to play BF4 on ultra and I thought if I went with a 770 I might not be able to do that. Of course nothing is for certain since the game hasn't been released, but I'm pretty sure the 780 will do the job I want...
Case= Case is a combination of style, functionality, and available space. If I had it my way this thing would be hanging on the wall. However, my wife thinks otherwise and I don't blame her. This antec case I feel has great airflow, great cable management, and great features. I wanted usb 3.0 on the front panel which surprisingly not everyone has yet. It also doesn't look like a military tire like another popular case, I like the more sleek design.
Power Supply= Reliability is the game, and Corsair is the name. I went with a non modular model because my case has plenty of space to hide all the cables. It works well and the 850w was overkill for my rig... I know can't have too much, plus 750 was sold out when I was ordering. The 850 also gives me plenty of headroom to do the SLI/Crossfire in the future if I wish.
DVD rom= I don't play blu rays, I don't burn blu rays. This one works great
Monitor= This also took me a long time to pick out. It is a solid 60 hz monitor. I thought about going 120 but in the end that would mean probably 2 way sli at least to get a 120 fps when I play BF3. This monitor is crisp and looks great on my desk.
Keyboard= I didn't want to spend a ton of money but I wanted the LCD display. It works okay, I can tell its a bit cheaper sometimes when i need to hold the shift key I notice just holding on the corner doesn't cut it. Its something I live with. For the money I feel its everything it should be.
Mouse= Love this mouse! I used to only ever have standard two button Microsoft mice but I wanted a few more buttons for gaming. This thing gives me two by my thumb I use constantly and also the on the fly dpi adjustments are something I didn't think I would use, but I find myself using all the time.
