i wanna upgrade my graphics card. I do not whether it is possible or not. Please help me with the information.It's now have radeon ati mobility 3450hd. So wanna change it. Pls help. i can spent 200-300$ for it.
Lots of great cards for under $100 these days(HD4850 deals have been $80-85 lately)
A case w/acceptable psu should be $50ish
500 gig HD $50
4 gigs of ddr2 can be had for $30-40 and below($20ish if you wait for a nice deal to come around)
A $70 e5200 c2d can be easily overclocked like crazy and is good for a budget gaming system. An AMD Kuma 7750 is $60 and offers similar performance although it doesn't OC quite as well.
An ok motherboard for the e5200 should be $50-70. Slightly less if you go for an AMD system.
That's all the main components for under $350. A dvd burner is $20ish... wireless card if you need one about the same. The system I just outlined should play any game quite well at reasonable resolutions, even Crysis. If you need a monitor too things get a bit more pricey and if you'd rather spend more for a quadcore system add another $50-100.
This will give you a good, highly overclockable, budget gaming platform complete sans monitor, kb/mouse, etc.
For another $30 or so, you can upgrade to a much more powerful 4850, if you can make it fit your budget.
