Will it work? 12 GB Ram ;6 core CPU; i7 ;9800 GTX

How much are you going to pay for that system?

If it costs more than about $200 USD total, forget about it. That CPU is about as weak as a cheapo dual-core Intel i3 CPU, based on the software-only MPEG2 performance results. That's because it's just the way AMD's Bulldozer-architecture CPUs work: In normal (default) mode, that "6-core" FX-6120 effectively behaves like it has only 3 cores. Even an eight-core AMD FX CPU is as weak as or weaker than a recent quad-core Intel i5 CPU which lacks hyperthreading, partially due to the default behavior of AMD's Bulldozer/Piledriver architecture CPUs.

And, you do need more drives than just that single hard drive to run most video editing programs smoothly. In fact, a single SATA hard drive will become completely choked by the demands of running an OS, performing system maintenance tasks, running programs and copying videos all on the same drive - and that's handicapped even more by the fact that SATA is only half-duplex and not full-duplex. As a result, the maximum I/O throughput of that single hard drive will be no higher than about 32 MB/second – far below what the drive itself is capable of physically.

And I stated all that because I don't want you to waste any of your hard-earned money on a six-year-old platform with below-average overall performance even for its vintage.

On the other hand, almost anything would be better than your current laptop, which for all I know is either so old or so low-end that it falls short of Adobe's minimum system requirements to run many of the programs within the Adobe CC suite.
