Last year in Nov, I made an AMD APU rig with the following config: [TABLE="class: grid, width: 500"] Mobo+CPU Gigabyte E350N Motherboard [TD="align: right"]4100[/TD] Cabinet Cooler Master Elite 310 Cabinet (Red) [TD="align: right"]1400[/TD] SMPS Corsair CMPSU-430CXV2UK 430 Watts PSU [TD="align: right"]2703[/TD] HDD 500 GB WD Cavier Blue [TD="align: right"]3300[/TD] RAM Kingston ValueRAM DDR3 2 GB (KVR1333D3N9/2G) x 2 [TD="align: right"]1156[/TD] ODD Samsung DVD Writer [TD="align: right"]900[/TD] [/TABLE] Now I am upgrading to Haswell processor. So, I bought an Intel Core i5 4570 processor from Amazon about a week ago, but so far unable to decide on what motherboard to use it with. Apart from the Mobo Combo, I am planning to use every other component, from above configuration. I may even built another configuration specially for the mobo combo which would be left spare with me after haswell upgrade (as planned). I am shortlisted these mobo's according to preference: ASRock H87 Pro4 Motherboard Gigabyte H87M-D3H Motherboard MSI H87M-G43 Motherboard Intel DH87RL 4th Generation Motherboard Now I selected only H87 chipset based mobo's since according to my research, its the best balance between performance and VFM. Core i5 4570 is not an unlocked processor, so I don't need a mobo which would help me to overclock, neither I plan to. I am not a pro gamer, so won't need to do crossfire. I did go out to get the mobo this saturday, but to my dismay I found no vendor kept the H87 mobo's except that of Intel, which was the last on my list. So I refrained to buy, and thought to ask fellow digitians before I try to buy it from Nehru place next saturday. I have the following doubts: 1. Does B85 and H87 really makes much of a difference? And what will I loose if I don't get H87 and get B85 instead. 2. How much difference does an ATX mobo really makes from a micro ATX one, for a basic gamer. 3. What other mobo's can I put in the list and what should be the order, since it seems availability of the mobos are scarce. (even out of stock on FK). 4. Should I care about getting a thermal paste, before I install the processor to mobo? 5. Should I care about getting new SMPS. I think no, since I am not adding a dGPU anytime soon. Please suggest.
