The intel one would be far better if you were to install your own graphics card as it does not have one, the CPU on this one is far superior though.
I think the AMD one would struggle to run relatively new games above low settings as the CPU isn't the best and neither is the graphics card.
Have you considered building your own PC? You would get better value and would be able to select the components that suit your requirements rather than buying a generic build some guy thinks will suit everyone.
AMD Bulldozer FX-4170 4.2GHz Quad Core CPU It's ok generally, top of their fx-4xxx range, but Intel will do better
8GB of 1333Mhz DDR3 RAMBranded ram and with heatsink just with the slower 1333mhz speed
2TB Hard Drive Storage SpaceOld tech hard drive
ATI Radeon HD 6670 2GB Graphics CardCheap version of 6670 with a barely decent cooler, will play modern games but on medium for good rates
High Performance Gigabyte MotherboardNot high performance, cheapest motherboard they can find, and is a mATX with old tech
Free Game Included (Worth £12.99!!)£4 game
Galaxy Gaming Case & 450W Standard PSUGeneric case and generic power supply which isn't efficient and brake down easily
Windows OS Not Included (Link to Upgrades Below)Need to buy your Windows
FREE 1 Year Warranty (Link to Upgrades Below)
Processors good, probably best choice for video editing and gaming...as i5 would struggle with video editing a bit.
Decent amount of ram, though not with heatsinks or at 1600mHz
Hard drive seems fine
Motherboard, again cheapest one they can get and is mATX.
Graphics is onboard, so you'll need to buy one and set it up.
Case is genericish and seems fine, add in a few fans...
No mention of power supply, most likely generic, again they are troublesome.
So technically the 2nd is better for video editing, but the 1st is better for gaming..........
Why don't you like other person said, build one?
Because getting a decent graphics card is around £85 which the 6850HD and then having to get a good power supply, another £40-£50
