^^ Okay the solution to this query is -- what do you expect of your PC?
--> Do you want to game,
--> day to day activities like movies, surfing, spreadsheet crunching,
--> entertainment hub, casual gaming,
--> strictly office PC,
--> heavy work primarly audio / video encoding / editing, 3D workload etc.,
after all this the major impediment is your budget.
Depending on your budget and work-load, you might get better performance from an AMD based solution OR an Intel solution --
core-to-core, clock-to-clock AMD processors fall behind Intel counterparts --
Tom's CPU Architecture Shootout: 16 CPUs, One Core Each, And 3 GHz : A Real (Theoretical) Performance Shootout, but on core based situations a cheap AMD quad-core will still hold its own to an Intel dual-core [Core i3 2100 vs. Athlon IIx4], in gaming on a low budget [Intel Core i3 2100 outperforms AMD quads], AMD Thubans [
hex-cores are purely number crunching monsters, their performance in games is abysmal also they sip a hefty amount of power at it],
for a HTPC / casual gaming RIG [
~30000/-] the best bet current days is the AMD Llano processor combining a Athlon IIx4 -- quad with a AMD HD 6550 IGP on the CPU die itself comfortably rips through most current generation games @full HD with low detailing --

For gaming on a budget [
~35000/-] get the Intel Core i3 2100 --

No comments on AMD Bulldozer as it has not been released and has no reliable data to back-up its claims [apart from company claims by AMD]. I hope this helps the situation instead of disolving it into a morass of Intel vs. AMD at price points. I've given a rough comparison of all Intel / AMD processors at the price points that I've mentioned, please check the links.
Hope this was a good read, Cheers Sire(s).
P.S. Iwould like to thank Dark Star Sir for his brilliant write up on the AMD Llano platform.
AMD Llano based laptops should make an entry in the Indian market soon, they've a good balance of gaming power [
indicative of the 3D processing capabilities] and processor power on the laptop front, better if you are looking for a gaming laptop which will have a spartan electricity affinity.
