@Jaskanwar-Now Lets compare Mine given rig with you.
I am not saying your config is bad but its needs some improvement.
Motherboard-MSI Z68A-GD65 over Gigabyte GA-Z68MA-D2H-B3
1)Full-ATX Board or m-Atx in Gigabyte
2Military Class II for The perfect trinity of quality, stability and efficiency all exist at one mainboard.
3)Hi-c CAP-8X lifespan over solid Capacitor.
4)Click bios is better in MSI
5)THX TruStudio PRO over Realtek ALC889
6)3TB+ Infinity-- All the latest 3TB hard drivers on the market can be supported
- Make the 3TB hard drive as boot disk when installing a 64-bit operating system
7)APS (Active Phase Switching)-Active Phase Switching, APS, technology is an intelligent design that helps to save energy on MSI’s mainboards
8)This board looks better
than gigabyte one.Looks matters for user who has transparent side windows.
9)MSI motherboard serviced by MSI India.Gigabyte is now serviced by ACCEL Frontline which is not good.Seagate also serviced by this company and many guys in our forum has experience it.After sales service as important as buying a new product.
Memory-G.Skill Ripjaws X F3-12800CL9D-8GBXM over G.Skill Ripjaws X F3-12800CL9D-4GBXL
1) 8GB dual channel DDR3 1600MHz 1.5V ram will give better performance than 4GB anyday.Nowadays more ram is better for power hungry games and multi-threaded application.
GPU-
1)Whats wrong with MSI GTX560Ti Hawk over MSI HD 6950 TF III?
2)MSI GTX560Ti Hawk-Costs Rs 14750/- and MSI HD 6950 TF III costs over Rs 16K
3)We can also use Hawk in Sli to gain extra performance.
4)If you use 6950 in CFX mode it will generate more heat than GTX560Ti.
5)Buddy compare product with same price bracket.Not with 6950 with 570.Compare 6970 with 570 or GTx 560Ti with 6950.
DVD RW
If we are spending to buy any system component every bucks is important.
1)Asus DVD RW over LG DVD RW- I am using Asus Dvd rw from 2007 with any problem but Tkin has purchased about 5 DVD rw including LG and Samsung.Finally he bought ASUS and he is happy with it.Many of my friend also complain about faulty LG RW.It lasts about 1 year or so.
PSU-
What you will get by spending extra 700 bucks for Tx850 over TX750?If you say it is always better to have higher wattage PSU.Why not you choose Tx950 V2 is only 800 more than TX850.
For Gtx560Ti Hawk SLi power comsumption is only 213X2 Watts as said by Topgear.So TX750 will do good.
Cabinet-
Coolermaster 690II Advanced over Lian Li Lancool K58W
1) Lian Li Lancool is not available throughout the country.And not all user are go for online purchase.Also shipping cost a lot for weighty cabinet.
2)Lian case looks very ugly.
3)All blacks interior was not there
4)Doesn't have 1.8" & 2.5" HDD and SSD adapter whreas CM 690II plus has this facility forget about advanced model
5)Cm 690II advanced has VGA card bracket
6)Build quality is better in Cm case.
7)Has provision to install
10 case Fans
8)Screw less mechanism is better in Cm 690II advanced
9)You can even remove the HDD cage to install GFX card like MSI 580 Lighting in Cm 690II Advanced.
10)Normal screw is used in Add-on card slot which is better than modern mechanism to tighten heavy card like GTX580.
11)Side intake fan is there in Cm 690II advanced.Which is very important for cooling card like HD 6950.Its not there in Lian.
So CM 690II advanced is better over Lian-Li Lancool K58W.
Monitor -
LCD has CCFL(Cold cathode fluorescent lamps) back lights.The immediate advantages of repalacing CCFL with LEd is a slimmer profile of monitor and also the power circuity can be kept in the power brick which can be attached separetely to the monitors unlike CCFL-backlit LCD monitor.
So Led monitor will be better choice.
Dell ST 2220L priced at Rs 8.75k but it will decreased a bit after few months.
Keyboard and Mouse-
1)I know Logitech G400 is still not available in Indian Market but still MX518 is there to fulfill our needs.G400 will available after MX518 becomes out of stock.
2)You can't compare with Microsoft Sidewinder X4+Logitech G400 or MX18 with Razer cyclosa bundle.Razer provides 1year warranty whereas Logitech gives 3 years and Microsoft gives 2 years warranty.
3)Backlighting with three illumination levels plus “off.” is there in Microsoft Sidewinder X4 where as backlighting is not there in Cyclosa bundle keyboard.
I think in general pc guide kolkata peoples are also included.In most of the states Rashi Peripheral is not good.That's why i am avoiding Rashi distributed product.So spending extra 3K makes more sense.
^for full hd even 6850 is sufficient.
And mention proof of 560ti sli almost near.
If 6850 is sufficient in Fullhd why you have bought Sapphire HD6950 1Gb.And why others purchasing GTX580 or HD 6970?
