I3 and i5 processor of intel

Hello,
i m in a li'l bit cnfusion...i want to knw which processor is better - i3 or i5- w.r.t running multiple os...becoz the only differnce between them is turbo boost feature nd a lil bit differnce in their clocking speed i.e. 2.1 for i3 and 2.3 for i5...but turbo boost feature of i5 is suitable for small apps as for high apps turbo boost will wrk until ovrheatng cndtn nd i hve to use two os simultaneously fr whch i thnk it doesnt go for long....so guyzzz plz tell me wht shuld i do...nd reply as early as possbl....

pls do reply.... i need to buy laptop urgently and confused between i3 and i5...pls suggest me ....

i5 2500s and i7 2600s are desktop cpus.
for laptops there's not much difference between i3 and i5 - both are dual core, both have hd3000 igp, both have 3mb cache etc.
the main differences between i3 and i5 are turbo boost - i5 can increase its speed to a higher level if a task demands it, core i3 can't. i5 also has aes-ni encryption acceleration, higher base speed than core i3 which means i5 will use more power on load. but it will get jobs done faster than i3. core i5 usually cost more.
if speed is your concern then get a laptop with core i5.
but compare all the laptop specs first and see which one meets your need the best.

thnks fr ur suggestion roy....i'll look fr it.....btw do u hve any idea which laptop can handle multiple os efficiently???

unless you will run heavy workloads frequently , i3 , without turbo will be good enough and heat less , more battery and also cost effective . for example i3 2330m , a current offering from many laptop vendors is for the most cases better than i5 2430 m (for example dell,hp in india)

ya u are right...hdd does is major concern but beside that i was sayin tht i want to run 2 os simultaneously at the same time....one is win 7 and other is linux... VMware workstation is used to run two or more os at the same time.....nd so it will require a lot of cooling mechanism as more heat woul be generated.....thts why i m asking about i3 nd i5 processors coz turbo boost wont go for long(in my case) and about a laptop which is efficient in handling heavy workload...

hmmm....thnks for ur suggestion...

ya thats why i looking for laptops with better cooling mechanism nd atleast 4 gb ram......Lenovo laptop's are qiuet good in tht case....na ya laptop cooler idea sounds interesting... 'll see to it... i luv to use a core i7 2xxxqm cpu..but wont have that much budget...hehe.....so will stick to eithr i3 or i5....

alternatively, you can check out a llano laptop with a 4-core amd a8 3xxx . llano cpus have 4 real cores(unlike intel core i5's logical/hyperthreaded cores) and igp more powerful than intel's hd3000.
llano cpus don't have vt-x or vt-d instructions. they have amd's version of virtualization support - amd-v. they can turbo up to 2.4-2.5 ghz using amd's turbo core, equivalent to intel's turbo boost.
llano laptops should be cheaper than core i5 laptops although laptop's price depends on overall specs. read tom's llano mobile cpu review for more info on that.
