No you cant, if you don't want a good gpu, then this might help you :/
AMD Phenom II X6 1090T - 19.2k
Gigabyte GA-880GM-UD2H - 8k
2 x 4GB DDR3 RAM - 7k
Creative Blaster X FI Titanium Sound Card - 6.9k
Thermaltake TR2 500W PSU - 4.5k
Exactly 45.5k :/ And more than 8GB RAM is no good if you're not into rendering and stuff, so 8GB is enough in my opinion

Or if you can increase your budget to 50k, then get another 4GB's

And a good psu is a must for a good processor, so yeah, risk na niye bhalo psu newa tai better
