Wouldn't beef be enough protein?
Totally! But usually for guys looking to really build a lot of muscle, and who have a very high protein diet, they would benefit from multiple sources of protein.
I mean, protein is protein! The advantage of multiple sources of protein is, 1) it keeps things interesting and 2) it eschews the development of food allergies.
Seriously if you ate nothing but chicken for 6 months your body might start to reject it. However, adding another 2-3 sources (even non-animal sources) of protein will help keep you healthy.
The list of proteins is huge! Also, the advantage of protein powders is that it's generally fast absorbing for athletes and individuals who strength train or whatnot.
Here's a chart I copied from a BBing forum.
"EGGS ( 1 medium size ).................6 grams
EGG WHITE (1 medium egg)...........4 grams
MILK (skim - 12 oz)......................12 grams
MILK (chocolate - 12 oz)................12 grams
SOY MILK (12 oz)..........................16 grams
TOFU (100 g)................................8 grams
LOW-FAT YOGURT (plain) 100g.....6 grams
FISH (cod fillets 100g)...................21 grams
TUNA (100 g)...............................18 grams
CHEESE (cheddar) 100g................25 grams
BEEF 100g...................................28 grams
CHICKEN 100g..............................25 grams
PORK 100g...................................21 grams
LAMB 100g...................................30 grams
BUFFALO 100g.............................28 grams
BEANS (kidney - 100g)..................12 grams
ROLLED OATS (100 grams)...........12 grams
Sausages (100g)..........................12 grams
Bacon (4 pieces or 35g)................12 grams
Turkey Bacon (4 pieces or 35g)......8 grams
Ham (100g).................................18 grams
Beefburgers (frozen - 100g)..........20 grams
Corned Beef (100g)......................26 grams
Luncheon Meat (100g).................13 grams
Meat Paste (100g).......................15 grams
Lentils (100g)..............................14 grams
Hummus (4oz).............................12 grams
Whey Powder (about 30g)...........24 grams average
100g = 3.5oz
100g = 3/4 cup
12oz = 350ml
A food with the highest protein total doesn't necessarily make it good for you.
Bacon has 12g of protein yes, but it also has about 15 grams of fat!
Another great read I came across is a comparison of known protein sources, however it shows the best vs. worst of each of these.
Top 10 Best & Worst Protein Sources (vegetarians take note) | Mark's Daily Apple
Protein Digestibility Corrected Amino Acid Score (PDCAAS)
A method of evaluating the protein quality based on the amino acid requirements of humans. The PDCAAS rating is a fairly recent evaluation method (it was
adopted by the US Food and Drug Administration (FDA) and the Food and Agricultural Organization of the United Nations/World Health Organization (FAO/WHO)
in 1993 as "the preferred 'best'" method to determine protein quality. These organizations have suggested that other methods for evaluating the quality of protein are inferior.
A PDCAAS value of 1 is the highest, and 0 the lowest as the table demonstrates the ratings of common foods below.
whey....................(1.0)
egg white.............(1.0)
casein..................(1.0)
milk.....................(1.0)
soy protein isolate.(1.0)
beef.....................(0.92)
soybean...............(0.91)
tubercules............(0.74)
vegetables...........(0.74)
legumes..............(0.69)
kidney beans.......(0.68)
rye.....................(0.68)
cereals...............(0.58)
whole wheat.......(0.54)
lentils.................(0.52)
peanuts..............(0.52)
seitan.................(0.25)

The more sources you include, the better. Generally beef is good for later in the evening because it takes longer to break down and will keep your body supplied through sleep etc.
Morning time is best for shakes and powders as you've been fasting throughout the night while asleep and when you wake up your body wants something quickly to absorb and use as energy!
My typical protein sources include:
Eggs
Chicken
Beef
Whey
Turkey
Fish (Tilapia, Orange Roughy, Tuna, Salmon, etc...)
I try to keep 3-4 sources going at all times! Also, proteins from legumes, grains, and some veggies count towards amino intake, but the ones from animals are considered complete!
