If you want to buy a new bike, get whatever you fancy. You don't need us to tell you how to spend your entertainment budget. Don't expect to go amazingly fast just because you've lashed out a ton of cash on a new toy. On Sunday I did a 10:57 lap on my 14kg MTB on a circuit where my PB is 10:10 on a <7kg carbon road bike, and there was bovine interference on the MTB lap :-)
