Transcend370 256gb is a nice one, or you can get a 128gb as well. there are other good ssd's as well, but I have not used these personally.
I wouldn't go for Transcend370. I mean, I did, a year ago, when that was the best option in the market at it's price. But there's better stuff out there now.
I've recently done a side by side review of a Transcend370 with a Patriot Blast. I must say, the write speeds are exceptional on the latter, even though your primary purpose is more often than not reading, when involving an SSD. For the price, I'd go for the Patriot drive again, haven't had hands on reviewing experiences with both drives.
That said, I'm not sure about the Pakistan market these days because I'm not in Pakistan right now, but if you can find a Samsung or an Intel drive in this budget, that's as good as it gets. Although, don't count on it. (i.e, finding Intel or even Samsung at that price point)
i was using ati 7970 and sold it last day now what would i buy in range of 25k ... any suggestion please i m having gs800 psu and i5 4670k with 8gb ram. also let me know is it really worth buying ssd ?
Is it worth buying the SSD?
Well, depends person to person.
If you ask me, it's been worth EVERY PENNY so far.
In a nutshell, advantages:
1- Unreal boot times
2- EXCELLENT access times and response times. Yes, it makes a LOT of difference.
3- Application load times reduced to a fraction.
4- Less power consumption (laptops)
If you go deeper, there's a lot more. But, my laptop is a world apart after the upgrade. Application load times are hardly a second, all around. Searching is fast and booting/rebooting is a matter of seconds, compared to a crapload of time to stabilize after a fresh bootup.
However, the only practical gain for you is pertinent to time. If the boot times and load times aren't something that matter to you, don't get an SSD.
