I wouldn't count on it. I recently got a similarly spec'd laptop [N2815, 4gb RAM]:
The dual core Celeron chips are anemic, at best. They are for casual internet surfing, listening to music, editing documents, and light video playing. The N2830, at least, has a clock speed that the N2815 in my laptop maxes on burst. I don't feel that ~300MHz extra would matter though.
The manufacturers do nothing to compensate for the CPUs either:
Even if you can swap the HDD for a SSD; it's SATA-II, and the benefits are minimized because of it. I put a Samsung 840 EVO in my laptop, and it feels wasted.
All the manufacturer's horrible specification listings verges on deceptive:
Dell states 1600MHz DDR3 in that model... which is well and good and all, except Intel seems to indicate current Bay Trail systems top out at 1333MHz. On top of that, many models only operate at 1066MHz- the $$ customers are charged for performance that is only on paper would be better allocated toward equipping the laptops with 8GB of adequately spec'd RAM that runs on less voltage (it's all part of the mainboard, so no upgrades there). My laptop has an 11.6" screen, and with the graphics memory 'sharing' the system RAM, I would expect much worse video performance with a screen larger than 11-13". Again, 8GB of 1333MHz RAM would improve the graphics performance, aiding to counter the CPU deficit. It makes you wonder who designs these systems, or why no one talks about over-segmentation of similar products is a losing situation for consumers.
If the model you referenced and my own laptop had the N2940 (twice the cores, twice the cache, SAME price of $107/tray from Intel), and 8GB of LV RAM that actually ran at 1333MHz, the motherboard was equipped with SATA-III + Intel RST, and there were a few more PCIE lanes for 802.11ac w/ the latest BT-4.0... that would be a nice little laptop worth paying around $340 for.
I only got the ASUS K200ma I am using now, because my 4yr old i5-450m laptop has issues not worth repairing (it can't run win8.1, and is largely incompatible with 8.0). I needed a basic machine with good battery life to get me through until the new 14nm Intel mobile chips and laptops built on them with an i5 arrive... so long as I can yank the HDD and RAM that comes in them, which to me is analogous to the paper stuffed in pairs of new shoes.
