CPU - i5 4570
Motherboard B85M-G - Asus (No PCI slots, only PCI express)
i5 4th gen - 4570
RAM - 8 GB (1600) - Kingston Hyperx
Gfx card - 650 Ti 1GB DDR5
HDD - WD blue 1tb
PSU - Corsair VS550w
Cabinet - Cooler Master K380
Under my max budget - (Rs. 50,000 / $800)
1. Motherboard has more than what I need in terms of SATA, Audio etc and no SLI/OC. No need for H87 or Z87. Chose ASUS over Giga for brand and better quality in general.
1a. Also thought of going for H81 chipset since max memory need will not exceed 16GB in fore-seeable future and by the time it does, it will be all DDR5 anyway.
2. Cabinet choice enabled very neat wiring thereby eliminating need for Modular PSU.
3. PSU is better than CX series (entry). TX is double the price and probably not worth the cost delta.
4. I regret spending time on exploring ready machines from Dell/Lenovo/HP etc.
You get half the value at this price point - 2 generation old chipsets, cramped cabinets and suboptimal PSUs leaving little room for expansion.
-I would look into 12GB Ram 1600MHz 3x4GBSticks
-change the HDD for an SSD, the performance of a SSD over a HDD is huge, loading times and boot times is far better but it does come with a price, if you can't expand your budget, a HDD for the meantime is fine.
-Good idea for the motherboard, no need to spend big bucks for something that has no performance advantage, the more you spend the more features you get but your covered for features.
-Great choice for a PSU, Corsair is very reliable and a trusted brand for a PSU....Great you didn't cheap out on a really bad PSU.
-Intel i5 Quad Core, those applications will need More then 2 and especially the way these 3D applications are going. And no point going for the k unless you are going to overclock, which I assume you aren't.
Overall, You planned quite well and for the budget it'll cost, a good investment for the work you do out of it and enjoyment.
If the performance of the graphics card is no need for you then the 7770 would be the better option. But for the software you need the 7770 is fine but since you do light gaming the GTX 650Ti is better for that.
But, There is one advantage over the 7770, You can crossfire them later (get two and connect them up as basically one), but that comes with it's disadvantages. The GTX 650Ti can't SLI (same as crossfire essentially), but the boost model can, so if you plan to get two cards down the track, get the GTX 650Ti boost or save the money and get a 7770. Integrated graphics is terrible, me after using integrated graphics 4000 was a terrible experience, not just gaming sucked but programs that required some graphics performance was not very good at all. I ended up with my build getting an R9 290X windforce 3x OC, but for 3D design and such both the 7770 and GTX 650Ti are perfectly fine cards for that and decent at gaming at medium on most games, Can play high depending on the game and your resolution. <That's for 1080p (1920x1080), which I'm assuming that's the resolution your working with.
