Will this run FSX well?

Some of you might remember me, I doubt it though. I stopped coming to this forum when I realized my PC was completely incapable of running FSX whatsoever. (And by that I mean less than 1 FPS on the lowest settings)
It's a HP Pavilion a1700n.
AMD Athlon 3800 64x2 Dual core processor
1024 MB RAM
250 GB hardrive
NVIDIA GeForce 6150 LE
OS: Vista Home premium
2 years after I bought it, I can buy this computer for the same price: $800.
Processor: AMD Phenom 9550 quad core processor
Harddrive: 640 GB
RAM: 6 GB
Graphics card: NVIDIA GeForce 9100
OS: Vista home premium.
Will the computer I'm thinking of buying run FSX at medium/low-medium graphics at at least 30 FPS?
