Should I go with the ASUS M32CD pre-built?

[BahdFish]

My main objective here is to be cheapest possible while getting the most gaming performance out of $820. I haven't used part picker before and I am a avid Amazon user with prime - I generally prefer buying all parts on Amazon for free 2 day shipping. My plan includes buying an Asus M32CD (pre-built) $440, 725w PSU $45, R9 390 $320, and a 92mm fan $15. I know what you're thinking with opting for a prebuilt but my reasoning includes the facts that it comes with decent cpu, hdd, free 2 day shipping and w10 OS.

 

My planned spec-list (All on Amazon):

1. $320 Sapphire 11244-01-20G Radeon Nitro R9 390 8gb GDDR5
2. $45 Sentey Xplus Power Supply 725 watt
3. $15 Fractal Design Silent Series R2 92mm fan
4. $440 M32CD Desktop (prebuilt):
   1.  i5-6400 3.3ghz oc 
   2. 8gb ddr3,
   3. 1tb 7200rpm
   4. windows 10
   5. Asus case w/ decent layout (upgradable space)
   6. Asus H110-I/M32CD4/DP-MB Motherboard

TOTAL: $820 + Free 2-Day shipping

 

*Is this a good plan considering that I do not have any real pc building experience, I want to stay with Amazon (for free 2 day shipping), and I want a high performance gaming pc? Will the mobo and or i5-6400 bottleneck my gaming significantly?

 

Games I want to play range from good cinematics like Tomb Raider or Batman to games like Rust and DayZ on high-max settings.

 

In addition to my purchases I have a few old spare parts lying around:

1. i7-870 (quad-core and w/ hyperthreading)
2. Crucial 250gb ssd
3. 2x8gb Kingston HyperX Genesis DDR3 8gb

 

Unfortunately, I am not sure if these spare parts still work, for they were sitting in a cheap ziplock bag, in a box, in our guest room (went through two moves). Another big question is that the Asus Prebuilt is also available in i3-4170 Dual-core 3.7ghz with no indication of a mobo change and for almost $100 less - so should I go with that instead then replace the i3 with my i7 (working presumably)? The problem is that I don't want to be stuck with an i3 if my i7 cpu does not work.

 

I am obviously a noob still so I need all the help I can get before I drop $800+ on a desktop. Thank you in advance for your help!

That i7 wont work in the prebuilt because it physically wont fit into a lga1150 board. You need a board with lga 1156 to use your i7. Also, that i5 which comes with the prebuilt is probably faster.

Thank you for the info! That is good to know. Does my plan make sense?

It seems to be good, although i would ditch the fan (most prebuilts come with decent fans) and get a better psu like a coolermaster G550M (80+ bronze, and modular for the small case).
