As you probably suspect, a GTX550Ti is nowhere near "high-end" gaming @ 1080p. I have shuffled your build, slightly, and included a good GPU. That slightly exceeds your $220, but hopefully I've made slight savings, elsewhere (bit difficult, without prices/budget on original build) PCPartPicker part list / Price breakdown by merchant / Benchmarks
I have kept case, as, presumably, you particularly like it. There are better options, performance wise, for your build, a lot cheaper. I note you've not included HDD, so I have left out, as well, although would be better, with one.
I really appreciate your help. And your configuration seems better than mine. I didn't include the HDD yes but i have got one 500 gb 5400 rpm. I'd like to know what other options can you provide.
And the problem is I live in Pakistan. Where not all the components you mentioned aren't available and will cost much more to import them from overseas. I'll try to search for them but for the time being can you give me the other option you were talking about.
And I would really appreciate if you could build one using components from this site too. http://www.galaxy.com.pk/
The figures quoted at the end are the prices of each component in Pakistani rupees, so I'd really appreciate if they when added together do not exceed 85000.
1: change to a i5 3450 or i5 3330. what ever is cheaper. no performance boost really by going with a i5 3570
2: id change for a asrock h77m motherboard if you have one. otherwise intel should be still ok
3:id get 8gb or 4gb.
4:get a hard drive. this helps you increase the budget for the video card
5:get a cheaper case like the antec 302 or antec 300
6: video card should be at least a gtx560 or a radeon 6870. the 550ti is the worst bang for the buck
7: coolermaster makes bad power supplies. suggest steering clear.
Then, virtually the only choice, that's reasonably suitable, of decent quality
PSU: Corsair GS600w @ 7600
If you are using 64bit Windows 7, it would be ideal to use 2x4GB 1600MHz DDR3 RAM, of decent quality. Unfortunately they don't have that as a "pair". The only way is to use 2 single 4GB Corsair XMS3, so
RAM: 2no. 4GB Corsair CMZ4GX3M1600C9 @ 2500 = 5000
If you are on 32bit Windows, use the 2X2GB version they do have, as 32bit can only use that amount of RAM.
For case, you could stick, with your original choice, although I can't see a price, unless several are the same price. What I presume would be cheaper alternatives, and reasonable quality, would be either,
Case: Antec 900 @ 8700, or
Case: Coolermaster HAF912 @ 8500
Both have pluses, and minuses, so I suggest you check some reviews, to see which you would prefer. Obviously, you are in a potentially hot environment. If you have air conditioning, not a problem. If PC is going to be somewhere hot, you may find you have to change, or add a fan. The ventilation, on either, is reasonable.
An SSD would be nice, for operating system, and games, but can't find any, on that site (maybe I'm not looking in right place). If the hard drive, you have, is SATA, ideally SATAlll, you could use that. If not, then perhaps a SEAGATE HDD (size to suit your needs)
If there is another site, whilst RAM and PSU will be OK, I would like to be able to offer a "better" alternative.
Hope that helps.
Here is another site I found which has some other things available too.
So here is a list of things I have gathered will be good enough, and the other components you've suggested, I have written to several stores asking for availability and I am sure I will have an answer in a day or two.
Seems to have slightly more variety, or at least different choices. You want DUAL channel RAM. Basically the same thing, 8GB but as a 2x4GB pair
That mobo is also suitable. I'm not sure I wouldn't slightly prefer the quality of the Gigabyte board, for a relatively small extra cost.
To be honest, I don't have any experience of those particular SSD's. Neither is a "top performer", but which is better, hopefully someone else can advise.
Definitely stick with the HD7870. Obviously, better (by say 20%, on average), unless huge price difference. Even then, generally best advice is, get best GPU, you can afford.
