Adobe and macbook pro not working well, can that be fixed? Whats the best portable format device for facebook games?

I got a surface pro 3 and it does not handle facebook games well at all. IT seems to be for two reasons based on advice I have received, intergrated graphics card and agressive throttling when hot.

I gave up on a tablet format device at that point and tried my husbands new high end mac book pro which has intergrated and dedicated graphics card. This handles it but the fan revs really highly and loudly and its still not quite as fast as my 4yo toshiba laptop. Any ideas on why its taking so much for the mac bok to run or what would be a good replacement device if I sell my surface pro 3? 

The Microsoft pro 3 is 256GB/Intel i5 version: 4th generation Intel Core i5-4300U CPU max 2.9GHz (with Turbo) with Intel HD Graphics 4400 8gb ram

  The hubbys Mac Book Pro is 2.8GHz quad-core Intel Core i7 processor Turbo Boost up to 4.0GHz, 16GB memory, Up to 1TB flash storage, Intel Iris Pro Graphics and AMD Radeon R9 M370X with 2GB of GDDR5 memory

The toshiba is intel i7 2670QM CPU at 2.20GHZ 6gb ram and nvidia geforce gt 540m graphics card

they are all using latest adobe flash
