Your build vs your friends build

CPU: no points given here, one is a Intel and the other is a AMD
M/B: Your friend: ATX 4 ram slots for future ram upgrades and system upgrade with the extra available PCIe slots.
Your's only has 2 slots so going with a 8Gb kit then there is no more upgrade path. Going with a single 8GB can lets you upgrade to 16GB, but that means
it's only running in single channel. Any only 1x PCIe x1 so adding any more further PCIe cards is severely limited.
RAM: Tie , both are the same
GPU: Yours, R9-290 is faster than R9-280x and has 4GB of vram ram compare to R9-280x which as 3Gb of vram
HDD: Tie, both of you choose the same exact HDD
Case: None Both of these cases lack front USB 3.0
PSU: Tie, you and your friend again have decided to use the same PSU
And the winner for who has the best build is....
None because both builds lack a DVD drive. No DVD drive = no Windows.
update: OP has again change his links. Both his and his friend have Intel CPUs and both have a R9-290 as their GPU
Your build: It's unbalanced, a unlock CPU with a low end H61 board. Not only that, the CPU has no future upgrade path. Socket 1155 and
Ivy Bridge is the end of the line for this platform. It would not be smart to spend your hard work money and buy something with no future upgrade path.
Your friends: it's also unbalanced, he went with a the highest i5 non K CPU and thought because it's locked, he can just also pick a low-end H81 board to go alone with it.
It seems both build wanted a high-end graphic card, with a system price that's as low as possible, which resulted in picking the cheapest parts.
If there is a winner here, it would be yours as least this updated config has a DVD drive to install Windows. If both has a DVD drive, then it would be
your friends because his motherboard can run Intel next CPU
