Gaming Laptop question, advice please

After about 10 years I've decided to get back to PC gaming.

I'm currently looking at Alienware laptops, as Dell is the only retailer I'd trust 100% in terms of component authenticity (I live in China) and it would have to be somewhat portable. I'm looking at Alienware 17 models from Dell HK, wondering about 2 options:

Option 1:

• 4th Generation Intel® Core™ i7-4700MQ processor (6MB Cache, up to 3.4GHz w/ Intel® Turbo Boost)
• 16GB Dual Channel DDR3L at 1600MHz
• 1.5TB RAID 0 (2x750GB 7200RPM) + 80GB mSATA SSD Caching
• NVIDIA® GeForce® GTX 780M with 4GB GDDR5
• Slot-Loading 8x SuperMulti Drive (DVD±R/RW)

Option 2 (different components bold):

• 4th Generation Intel® Core™ i7-4800MQ processor (6MB Cache, up to 3.7GHz w/ Intel® Turbo Boost)
• 32GB Dual Channel DDR3L at 1600MHz
• 256GB mSATA SSD Boot + 750GB 7200RPM SATA 6Gb/s
• NVIDIA® GeForce® GTX 780M with 4GB GDDR5
• Slot-Loading Dual Layer Blu-ray Reader (BD-ROM, DVD±RW, CD-RW)

Option 2 would cost an additional 900 USD!

Application would be of course gaming, but also music production (mostly Reason and FL).

Given that

a) I don't really care about the Blu-Ray reader and

b) I'm assuming the extra 16 GB RAM of option 2 will not significantly increase gaming performance = don't really care

Will the differences in processor and hard drive(s) of option 2 increase performance a lot? I know it's all relative, but just to give an idea, I'd like to be able to play most current and upcoming titles with decent and enjoyable settings and not have to look at upgrading for a year or two.

Cheers

P.S. I know there are options with far better price/performance ratios, but as mentioned, component authenticity is a big problem here, so Dell it is.

Ok, at the risk of being repetitive:

I'd like to know if you guys think the performance difference for gaming would be significant / warrant the price difference.

I respect everybody's opinion on what they would and would not buy, but I don't really need input on that as I explained the market situation here. Thanks folks.
